Butterfly Conservation Ireland

It is 29 July as I write, and the summer is flying sunnily by. Despite the glorious weather, populations reported from across the country are low in most cases. Where high numbers are observed, these are usually of two migrants, the Red Admiral and Painted Lady. In short, hot, sunny weather is great for Ireland’s butterflies, but it’s just one ingredient needed for the meal. More resources are required to provide a happy home for butterflies. One explanation for low numbers is the scarcity of resources needed to grow and sustain populations. Populations reflect the carrying capacity of habitats as well as weather and predator populations. With 90% of EU-protected habitats in unfavourable condition, the reason for low abundance is clear.

Despite the ‘great thinning’ of the fabric of the natural world, our butterflies will still fly in August, despite diminished figures.

Here are the species we can hope and expect to encounter.

Part of Butterfly Conservation Ireland’s strategy to save our butterflies is to advocate for the protection of high-nature value land, especially land in public ownership.

The Bog of Allen in North-West Kildare and East Offaly is such an area. The quality of the habitats is clear in spring and summer, when the abundance of invertebrate and bird life cannot fail to impress.  The bird life over the winter months is impressive, with Whooper Swans, Golden Plover and Lapwing in good numbers. There are five areas in the region set aside for nature at present, but all are small.  One is Butterfly Conservation Ireland’s reserve in Lullybeg. The overall area of the bog is estimated at 5,581 hectares.

A proposal to create Ireland’s largest, tallest wind farm, complete with over 60km of industrial road, would deliver a devastating blow to the region’s nature and nature restoration. This flies in the face of the need to restore habitats in 20% of Ireland’s land (and sea) area by 2030 under the EU Nature Restoration Regulation. We have produced a campaign leaflet to highlight this important issue. We propose that a National Park be established in the region. Ireland has no national park in the midlands and no national park on deep peat.

The leaflet, a collaboration by various conservation organisations, contains advice on what we need you to do.

All Kildare politicians need to understand your feelings on this vital issue for nature.

What do warm nights, a great location, friendly people and the right time of year make? A great moth morning. And what a great cache of moth treasure we accumulated in four Robinson traps in Dara and Maire’s garden in Prosperous, Kildare. The garden holds ponds, mostly native trees, scrub, hedges, grassland with native wildflowers and some well-chosen garden flowers such as Fennel. The garden adjoins bogland and Scots pine woodland with resident Barn Owls.

Sounds perfect? That’s what it is!

The moths clearly find it so, all 100-plus species registered so far. Despite a cooler night than recently (it fell to about 11 degrees), there was much to see. The traps were full, and Philip Strickland’s moth-identification skills proved very useful as some unusual species appeared. Key among these is the Suspected, a species declared extinct by the state in the 2016 Macro-moth Red List. The moth is thriving in this lovely area, if the dozen or so in the various traps offer evidence. Since 2010, there have been records for just 11 10km squares, 1% of Ireland’s 10km squares.

Other local species found were Bordered Sallow, Scarce Silver Y and Barred Rivulet. We found Broad-bordered Yellow Underwing, relatively well distributed in the east, but very scarce west of a line from Sligo Town to Wexford Town.

There is one disturbing note. We again failed to find the Garden Tiger moth,  recently common. Has it disappeared from Kildare? If so, it must be lost from many areas. It breeds on common plants, such as Common Nettle, Broad-leaved Dock, Common Dandelion agg. and many other plants. We are not diagnosing a foodplant shortage for its disappearance, but perhaps the quality of the plants and the nature of the adjoining vegetation have altered. The disappearance of a large, colourful, much-loved species is a great concern, especially as it was common until about 2015.

Our post-trap conversations are typically eclectic, warm and humorous, and this was no exception. Thanks to Philip Strickland for organising the event, Dara and Maire for hosting us, and everyone who attended.

We are having a bizarre year for weather, and this erratic weather might become embedded, becoming the climate. We had extraordinary rainfall in January, February and March, and record heat in May, with the record for that month broken twice by more than 2 °C.  The highest air temperature ever recorded in Ireland in May was 30.6 °C on 26 May, at Shannon Airport. A heat wave was also recorded in June, when maximum temperatures again exceeded 30 °C.  Regarding winter rainfall, Dublin Airport’s February rainfall was 255% above the long-term average and the highest since rainfall records began 84 years ago. February and March temperatures were above average, but January was both wetter and colder than usual.

This meteorological background raises questions about how butterflies respond. Extreme heat in summer is beneficial for the adult and pupal stages and extreme precipitation has been found to damage the pupae (especially) and larvae of single-brooded butterflies (most Irish butterflies (21 out of 35) are single-brooded, i.e., they produce one generation each year).

The single-brooded butterflies are especially sensitive to extremes of heat and cold; the adult is sensitive to extreme cold in summer and extreme heat in winter, while the overwintering stage of single-brooded butterflies is sensitive to extreme heat in winter. It must be noted that single-brooded butterflies overwinter in all four life stages. (The overwintering stage depends on the species, but the larval stage is the most common overwintering stage.) In addition, extreme precipitation during the pupal stage drives negative population change in a number of single-brooded butterflies.

What about our multi-brooded species?

Extreme heat during overwintering and extreme precipitation during first- and second-generation adult life stages are the most frequently occurring extreme variables causing population declines in multivoltine species (67%, 58% and 50% of all multivoltine species affected, respectively). As in single-brooded species, adult and overwintering life stages have opposite population responses to temperature extremes. Extreme heat during the adult life stage (outside winter) is associated with positive population change in 42% of species.

Drought plays a much more important role in multi-brooded species than in single-brooded species. Drought negatively affects 50% of species during their second larval life stage, but has a positive impact on 25% of species during their first ovum life stage.

The study, carried out in the UK, found that multi-brooded butterflies are more sensitive to extreme climate events than single-brooded species, with all life stages, ovum, larvae, pupae, adult and overwintering represented in the nine most important variables in the combined model.

Extreme precipitation during the overwintering stage does not significantly negatively impact multi-brooded species or single-brooded species. This is very good news, because last winter was extremely wet and not extremely warm.

A striking feature of this summer’s butterfly story is the Ringlet population, which, where I look, is the largest I have seen for about 10 years. It had declined in my area of County Meath, with low numbers in what appear to be excellent habitats. Last year, I counted a mere 17 Ringlets on my South Meath transect. On June 25th, I counted 22 Ringlets there during a single visit. It is proving abundant in NE and NW Kildare.  The Meadow Brown, another single-brooded butterfly, is numerous too. Orange-tip, a spring flyer now finished its flight period, was numerous this spring.  Weather/climate is not the only influence on populations, but it is a key framework for species presence and population size.

Despite their sombre appearance, our Ringlet and Meadow Brown populations must not be overlooked, and counting them provides data on how our grasslands are performing and how weather and climate influence the habitats and populations.

We can also look forward to seeing our largest and most glamorous species in July. The first Silver-washed Fritillary of 2026 is due any day, and the first Dark Green Fritillary reported to our recording scheme this year appeared in Portrane, Dublin, on the 25th of June. We await our first Brimstone and Peacock, but the first brood of Commas has already made their appearance; these have so far been the golden form, which breeds immediately after emergence. Later in July, some dark-form Comma butterflies will appear. This form delays breeding until next spring.

The Small Tortoiseshell’s first brood is now flying. These are the children of those who passed the winter as adults and bred in spring. The new generation is behaving like the golden Comma, and is mating and laying eggs. These will produce a second generation that appears in August and September. However, a few Small Tortoiseshells will not breed and will enter an overwintering state, with dark form Commas. This flexibility allows Irish Commas and Small Tortoiseshells to capitalise on good conditions in warm, sunny summers with good rainfall while setting aside some individuals to delay breeding to safeguard against the onset of unsuitable conditions later in summer.

The highly unpredictable weather in Ireland can drive people to distraction. Last winter was dreadful for one’s mood, with miserably wet, dark weather for several weeks. However, our butterflies survived, and some are doing quite well this summer. Their colour gives us something to look forward to and enjoy, while their current abundance highlights their resilience in the face of meteorological adversity.  There’s some comfort in that for us!

But we must be on our guard. Extreme heat during winter is bad news for butterflies. Our climate is predicted to have hotter summers, which is good for butterflies, but warmer winters, which are detrimental. Will the benefits of warmer summers be outweighed by the negative winter effects?

Keep counting our butterflies…

The recent hot, sunny weather makes everything outside look brighter. Winged insects can move with ease, finding it easier to feed, seek mates, lay eggs or move through the landscape. In Britain, and presumably in Ireland, extreme heat is associated with better outcomes for most butterfly species.

In this post, we look at some native wildflowers that bloom in June.

The Bloody Crane’s-bill flowers from May and throughout June, with repeat flowering into the rest of the summer and early autumn. It is used by hoverflies, bees and butterflies, and is easy to grow, though it favours lime-rich, free-draining soils.

The Smooth Hawk’s-beard is common and often abundant on dry grasslands. It reaches up to 1m and has hairless stems and glossy, pinnate leaves. It is among the top 20 flowers in Ireland for supporting high pollinator diversity (see (e) below). It also ranks highly for (a), average abundance of visitors, (b), average species richness of visitors, (c), betweenness centrality (how connected it is in the plant-pollinator network) (d), duration of bloom, (e) and functional complementarity (supporting different insects).

Upright Hedge Parsley looks a little like Cow Parsley but comes into flower later and is a more delicate flower, and often has a pinkish tinge. It occurs beside hedges, often in dry places. It does not appear to be the foodplant for any of our butterflies or macro-moths, but it is a nectar source and is rather elegant. It has been recorded as a larval foodplant for the Southern Swallowtail butterfly, a southern European species.

This fragrant flower is used as a larval foodplant by some beautiful moths, such as Small Elephant Hawkmoth and Hummingbird Hawkmoth and several carpet moths. It likes dry grassland and has a beautifully evocative honey scent. The plant has several medicinal uses and was even used as an alternative to renin to coagulate milk in cheese production. It deserves a place in any wilding project, for its colour, fragrance and overall value for the grassland ecosystem.

This tall, multiflowering biennial or perennial flower is a considerable draw for nectar-feeding invertebrates. Painted Lady butterflies are especially keen on its flowers. This also needs dry situations and can grow in very shallow soil.  In warmer countries, it seems to attract much more attention from butterflies than it does in Ireland, with Six-spot Burnet moths drawn to it, sometimes in their hundreds!

This common flower can be white, pink, purplish, and it varies in height too. It is used for nectar by some butterflies, including the Silver-washed Fritillary and Marsh Fritillary. It occurs in dry grassland and will hybridise with Heath Spotted Orchid. It will appear in gardens that are not treated with fertilisers, and is a sign of undamaged soils. It is used as a foodplant by the Buff Ermine moth.

This tall plant is usually found in wet places, such as wet grassland, fens and river and canal banks. It is a rich source of nectar for many insects.

This fragrant wetland plant with its fragrant, frothy, creamy blooms epitomises summer. The flowers seem more important to bees, but butterflies will use them too. The leaves are eaten by Emperor Moth caterpillars, and by caterpillars of other macro-moths, such as Sweet Gale, Powdered Quaker and Hebrew Character.

Many plants that have finished flowering for the year are very important for pollinators, especially for their immature stages. The flowers of Blackthorn are eagerly used by spring flying moths and butterflies, but their leaves are food for larvae, notably by the Brown Hairstreak butterfly.  About 54 macro moths feed on the plant, including the Brindled Beauty.

The overall message is, go native! These are the plants that feed most of our insects. Many non-natives are poor for pollinators, and some are invasive and damage our environment. Go native!

Corfu is reputed to hold high biodiversity, including butterfly populations. Armed with advice from Ionian Butterfly Conservation and the Field Guide Corfu produced by the European Butterfly Monitoring Scheme, we decided to see this for ourselves. We were not disappointed.

Corfu sits in the Ionian Sea, just 2km from Albania and about 10km from the Greek mainland. It is about 593 square km in area, c.57km in length, and about 28km in width at its widest point. The north is especially well wooded, with about 36% of the island under tree cover, although much of it consists of Olive plantations, mostly hundreds of years old. The economy is mainly reliant on tourism, but olive oil production is also important. Central and southern Corfu are the main agricultural areas. The island has about 101,000 residents, most of whom speak English. Corfu town holds about 40% of the population. Corfu has a Mediterranean climate, with hot, dry summers and mild winters when most rainfall occurs. The island is remarkably green, a feature striking for those familiar with the Mediterranean region in summer.

We visited from June 2 to June 13, and daytime maximum temperatures were typically 25-27 Celsius, with night temperatures about four Celsius lower. We focused mostly on the northern areas, which we heard were rich in butterfly populations. We were not disappointed!

The best areas for butterflies were the open flower-rich edges and clearings in scrub, woodland, and olive groves, and along the tracks through these wooded areas. The soils are calcareous, and the clay soils, especially notable along the coast at Agios Georgios Pagon in NW Corfu, appear to retain moisture. In NE Corfu, near and around Mount Pantokrator, the terrain is rocky. It contains a mixture of bare and sparsely vegetated ground, native woodland, grassland and scrub known as Maquis, the term used to describe evergreen scrub in the Mediterranean basin. Common scrub species include Strawberry tree Arbutus unedo, Lentisk Pistacia lentiscus, Myrtle Myrtus communis, Holly Oak Quercus coccifera and buckthorns such as Mediterranean Buckthorn Rhamnus alaternus and Jerusalem Thorn/Christ’s Thorn Paliurus spina-christi.

Grassy areas along roadsides were also rich in butterflies. In some areas, the populations were so large that people gazed at the spectacle. This included areas in coastal villages, where Cleopatra butterflies mixed with Large and Small Whites, Painted Ladies and Southern White Admirals to feed on garden flowers, especially the non-native reddish-purple climbing plant Bougainvillaea.

The various trails through the landscape, especially the donkey trails, were very rich in butterflies. We walked part of the donkey path from Makrades village toward the coast. Limestone cliffs edge part of this walk, with interesting flora in the narrow strip between the cliff and path, excellent for butterflies. We found the umbelliferous plant Scaligeria napiformis, a foodplant for the extremely range-limited rare butterfly used as the symbol for Butterfly Conservation Corfu, the Southern Swallowtail Papilio alexanor, the only European butterfly that roosts with wings fully extended.

We found the caterpillars, black, white and orange, busy chewing on the seeds of the foodplant. When disturbed, it raises a fleshy, yellow organ from the first segment behind the head, producing a fluid that stinks of rotten pineapple. Presumably, this deters birds. Later in our stay, I found the caterpillars on Giant Fennel Ferula communis at sea level near the coast near Ipsos/Ypsos, NE Corfu. In Europe, it occurs only in small areas of SE France, NW Italy, W Croatia, parts of Greece, usually in mountains, Albania and the Republic of Macedonia, and its occurrence within these areas is local and sporadic.

Corfu has four papilionid (swallowtails, festoons and apollos) butterflies, three swallowtails and the Eastern Festoon. The swallowtails present are Common Swallowtail Papilio machaon, Southern Swallowtail Papilio alexanor and Scarce Swallowtail Iphiclides podalirius. In Greek mythology, Machaon and Podalirius were sons of Asclepius, while Alexanor was a son of Machaon. Given their legendary roles as Greek deities, these butterflies should occur in Greece. All are stunning, floating in warm breezes with insolent ease. They are swift in flight, often fluttering teasingly close only to vanish when the fancy takes them. All these large, showy butterflies usually feed by fluttering over their flowers, standing on them on tiptoes, their heft too great for most flowers to support them.

We caught glimpses of the Scarce and Common Swallowtails, but neither was numerous during our visit. Neither needs habitats of special character and can turn up anywhere, from exposed hill-tops to cosy gardens. The only chance of getting that good photograph is to find one early in the day, when they perch in warm, sunny places to heat their flight muscles for the day’s activities.

We found several species we have in Ireland, with the Brimstone (uncommon, but likely we were early in the flight period), Clouded Yellow, Wood White, Large and Small White (abundant, widespread), Small Copper (low numbers), Common Blue (abundant), Holly Blue (widespread but not numerous), Red Admiral (occasional), Painted Lady (widespread, numerous), Silver-washed Fritillary (widespread but not numerous), Speckled Wood (widespread but not numerous), Wall and Meadow Brown (widespread and abundant), Small Heath (in low numbers on short grassland), and Small Skipper (widespread but not numerous). The others we share with Corfu that we didn’t see, such as Comma and Peacock, might have been in the immature (non-adult) stage.

Overall, Corfu has 76 butterfly species; we saw 38, possibly 40 (Long-tailed Blue and Green-veined White might have been seen). We missed the spring flying species (April appears to be the key month).

It was wonderful to see ‘new’ species, like the Southern White Admiral, a graceful flyer that occurs in areas with trees, shrubs and hedges, including gardens. Males are notably smaller and patrol their habitats using regular flight paths and perch points. The smart deep black and starched white uppersides contrast with equally smart brick-red and white underwings. The most exciting finds were three grayling species, Delattin’s Grayling, which looks very like our Grayling, Great Banded Grayling and Eastern Rock Grayling, the latter two large and dramatic in flight, and equally happy in hot, dry woodland with clearings and open scrub and even hot, rocky places with low, scattered scrub.

The stunning Cleopatra butterfly/Mediterranean Brimstone was seen everywhere, from beaches to gardens, roadsides and rocky mountain slopes. Males are straightforward to identify; they have sulphur uppersides sporting a deep orange forewing flush. Females are much trickier. I saw many large females with whitish-yellowish uppersides (normal form), very similar to the female Brimstone with which it is easily confused. However, some females, especially in SE Europe, including Corfu, have pale yellow uppersides and even the deeper sulphur uppersides, like the male Brimstone. We saw all three colour forms, and it took me a couple of days to be sure about what I was looking at. The Cleopatras were absorbed in feeding up for ‘winter’. It hibernates from the end of August, reappearing in February, although it probably breaks hibernation to feed after August. It was obvious that the heat in more exposed areas, even during late morning, was quite extreme, as individual Cleopatras and Brimstones frequently entered bushes to seek the coolness of shade.

The butterfly that shocks the spirit is the Two-tailed Pasha. Large, showy and fearless, it is impossible to be unimpressed by this powerhouse. My first glimpse of the butterfly was obtained while driving to Agios Georgios in NW Corfu on our first morning, when a hot pursuit over the road was sighted. A head-turner, this swift butterfly would be impossible to approach if it so chose, but it is so fearless that it allows you to eyeball it. It looks weirdly shark-like in outline, and its dark eyes have an opaqueness that allows no insight. It returns human gaze with dark, unreflecting eyes, suddenly surging into the skies to attack an intruding male. Step away from his launch site, and this Exocet invariably returns to its post, bristling with aggression.

It breeds on the Strawberry Tree in open areas, and it likes maquis habitat on hillsides. Double-brooded, it is a tropical species restricted to the southern edges of Europe, usually near the sea. Seeing this species fulfilled the dream of a lifetime.

Another lovely butterfly we saw, and in great numbers, is the Balkan Marbled White (BMW). Despite being numerous (we saw around 200 in and near Old Perithia), it is geographically restricted, found only in SE Europe (also in Turkey, Transcaucasia and N Iran). The lovely black and off-white marbling patterning is classy and striking in an understated way. Like many butterflies, it was strongly attracted to scabious flowers, especially Sweet Scabious Scabiosa atropurpurea. Newly hatched BMWs are easy to observe and photograph. After a few hours, males become active, feeding and mate-seeking during sunshine, settling quickly in overcast weather. This response to cloudiness was noted in all the butterflies we observed.

Another interesting butterfly is the Lattice Brown. It is large, about the size of the Red Admiral, and quite skulking. It rarely appears in the open, fluttering in shady scrub, Bracken and trees, where males scour the branches, doing circuits of the tree limbs, presumably looking for love while females prospect for egg-sites (it lays on trees). It is extremely hard to approach, and the dull light of the woodland does nothing to conceal the human approach. This orange and brown phantom of the forest is agile and ghostly, a spirit that melts into the earthy tones of hot shade. It is confined, in Europe, to the SE.

Large, Small, Mallow and Lulworth Skippers were widespread, with the Lulworth Skipper particularly abundant. Another eye-catching butterfly is the Spotted Fritillary, especially the orange-red males. This is probably the commonest fritillary in Europe. We also spotted the Southern Comma; brighter and paler than the Comma, it likes basking on rock and breeds on Pellitory-of-the-wall.

Butterflies were found elsewhere, but special hotspots are Old Perithia, a beautiful 14th-century village in a breathtaking setting, the areas immediately inland of Agios Georgios, accessed by tracks through olive groves and the donkey path from Makrades. I am tempted to visit in April for the spring butterflies!

Looking at the abundance and at how widespread the Corfiot butterflies are, one worries more about the state of Ireland’s species. However, there are some concerns. Some olive growers use herbicides under the trees, eliminating important grasses and flowers for nature. This was unsightly and destructive, and no butterflies were observed in poisoned areas. Many olive groves were not poisoned, and these are great for insects. Like many residential areas in the Mediterranean region, garden flowers are grown instead of natives, but gardens are not extensive enough for this to be a major problem.

The scenery throughout the northern half of the island is simply spectacular. This might be true of the South, too. People are helpful and friendly, and the food is excellent with options everywhere in towns, villages and on seafronts. The roads are often narrow, and upland roads contain many sharp bends, so slow, cautious driving is essential. The island is green, despite the Mediterranean heat and dryness, quite different to nearby mainland Greece and Albania. No wonder Gerald Durrell called it ‘The garden of the gods.’

The rare Marsh Fritillary butterfly, Ireland’s only legally protected insect, ranked Vulnerable on Ireland’s Butterfly Red List, continues to thrive at Lullybeg Reserve. Butterfly Conservation Ireland members monitor butterfly populations on the reserve. One of our members, Pat Wyse, counted 24 adults along the transect route through part of the reserve, with more uncounted off the transect. Only butterflies along the fixed route are counted according to the methodology; butterflies 2.5 metres either side and five metres ahead and above the walker are recorded.

Lullybeg is managed for butterflies, with grazing, scrub control, and soil disturbance applied to selected areas to benefit all butterflies present in the reserve.

The sight of beautiful adult Marsh Fritillaries on the wing in May and June is a reward for the hard work of our supporters and members, and an incentive to continue our stewardship.

The Marsh Fritillary continues to thrive in Lullybeg, but for how much longer? Listen to the interview with RTE’s Philip Boucher Hayes conducted on Lullybeg Reserve on 26th of May (from 38 minutes to the close): https://www.rte.ie/radio/radio1/countrywide/episodes/11799226/

Thanks to everyone involved in the reserve’s management. Enjoy the photographs.

 

Irish weather is the proverbial box of chocolates, but we got the choicest confectionery for our well-attended event today. Not too hot, dry, sunny, gentle breeze…perfection.

The next question is, what will we see? Will the poor weather in previous weeks limit the variety on offer?

It limited the number of butterflies we could expect in good weather in late May, but not the diversity. Dingy Skipper, Cryptic Wood White, Green-veined White, Orange-tip (adults and caterpillars), and a large Brimstone population, including females giving a close view of laying on Alder Buckthorn, Common Blue, Holly Blue, Red Admiral, Painted Lady and around 30 Marsh Fritillaries,  very active, chasing one another, chasing Four-spotted Chaser dragonflies (reckless, misguided and potentially fatal behaviour!).

Moths abounded, with Burnet Companion, Common Heath, Mother Shipton, Narrow-bordered Bee Hawkmoth, Pyrausta despicata and a nice rarity, Small Chocolate-tip.

Dragonflies were everywhere, especially Four-spotted Chaser, Hairy Dragonfly, Large Red Damselfly, Variable Damselfly and Blue-tailed Damselfly.

The habitats were in good condition after our grazing, scrub-cutting, and calibrated soil disturbance, creating a diversity of sward heights and ground conditions. All we need for the reserve’s butterflies and moths to take advantage of these conditions is the right weather.

It was reassuring to see several frogs of a range of ages, so our wetlands are likely to be in a good state.

It is wonderful to see so much nature in beautiful, unspoilt, quiet habitats. All wild things need a good home, and they have it in Lullybeg…for the moment.

The other really satisfying part of the day was enjoying this beauty with lovely people who appreciated the experience of our special nature and special places. Everyone took great interest in the activities taking place, and hopefully took lovely photographs. A couple of butterflies sat on human arms and hands, a lovely intimacy with the airborne gems of our boggy places.

One Four-spotted Chaser dragonfly, netted to give everyone a nice view, sat on an arm when released, re-orientating itself after its brief captivity. Its beauty was amplified when the gothic tracery of its wings was cast as a shadow on bright skin. Close observation and gentleness reward us with beautiful memories.

Nature and our enjoyment and experience of it confer so many advantages: spiritual, aesthetic, physical, and a sense of community. Long live Lullybeg.

We had a leisurely walk, for only by close observation will nature be appreciated.

Thanks are due to everyone who joined our event today. Enjoyment is more profound when shared.

The Irish weather seems to enjoy turning nasty on weekends. Ask anyone working all week indoors when the sun is shining.

The forecast for Saturday promised nothing useful to our butterfly expedition to two Burren localities: Fahee North in the morning, and Burren National Park after lunch.

Cool, grey and windy spelt no butterfly action, but our lovely group were determined to enjoy the rich habitats on show. We did see the key larval foodplants for rarities like the Marsh Fritillary, impressive ant-hills sporting Wild Thyme holding fat, well-nourished Transparent moth larvae. It should be a good June for the striking adult moths. The grassland on the site we walked is managed by organic farmer Hugh Robson, who kindly allowed us access.  Carefully grazed and scrub-controlled, this site is superb for butterflies, holding all four fritillaries, two blues, Brown Hairstreak, Small Copper, all the Burren’s brown butterflies, all the Burren’s whites, and the expected Small Tortoiseshell, Peacock, Red Admiral and Painted Lady.

Adjoining is a very different habitat: open scrub on shattered limestone pavement grazed heavily by horses, creating ideal conditions for the Pearl-bordered Fritillary and Dingy Skipper. Just as we were leaving, the sun entered, as did the Pearl-bordered Fritillary and Wood White. I missed the latter, but photos were taken and produced in evidence!

A drive, a bite of lunch and part II began with a visit to the Burren National Park. We walked the Orange Route, which takes you through Limestone grassland, scrub, Knockaunroe Turlough, Ash/Hazel Woodland and finally to a lovely area of warm, dry grassland dominated by ant hills. The sun shone most of the time and made for a very rewarding experience.  A couple of over-the-hill Brimstones hoved into view and into my net when we held our collective breaths in admiration of a butterfly already 8-9 months old and still feisty.

One of her children was found on a Purging Buckthorn near the turlough. This little green caterpillar was lined up along the leaf midrib, blending greenly with the fresh, gleaming emerald of the foliage.

The scrub at this point is unusually rich, with abundant buckthorns, Hazel, Ash, Guelder-rose,  Hawthorn, Blackthorn and Shrubby Cinquefoil. For the record, the turlough was dry. The area is warm and sheltered and heavily favoured by Wood Whites.

This delicate creature occurs only on exposed Carboniferous limestone in Ireland, making it one of our rarest butterflies. It is currently known from just 24 10km squares, 2.35% of Ireland’s 10km squares.

Dingy Skipper and Burnet Companion waited for us in the ant hill grassland. They darted in the sunshine, in a warm, quiet place that invites you to linger. Looking at this area, it is notable for the small-scale diversity now so often absent from our landscapes. Ant hills, short, medium-height and tall vegetation, low bushes, tall scrub, and woodland in the vicinity provide niches for a great range of plants and invertebrates, including some cheeky grasshopper nymphs.

Just as our time was drawing to a close, a White-spotted Sable sparkled in the May sunshine. Perhaps summer will be good to us.

Sunday dawned wet, brooding and chilly. Our walk was planned for Clooncoose Valley, and we started the walk in cold rain more typical of February than May. Luckily, the valley is sheltered, and the track heats even in weak sunshine. We saw a solitary Speckled Yellow moth, surely one of our prettiest day-flying moths. We discussed butterfly ancestry, genetics and the history of butterfly recording during a dry period. We looked at important breeding plants, including Common Dog-violet, until very heavy rain precipitated a retreat to prepared positions.

Warm cars awaited, thankfully! However, despite the deluge, we had a lovely time and hopefully learned lots. Thanks to Brian Nally and the team at Burrenbeo Trust, and to everyone who travelled to these well-attended events. I certainly enjoyed the company and sharing time with people who appreciate nature and the Burren.

Our next event is a walk in Lullymore and Lullybeg on Saturday, 23rd May.

One of the benefits of having a grown-up family is that, occasionally, a marriage is celebrated in a foreign clime, allowing one to seek unfamiliar butterflies or see how familiar butterflies behave elsewhere.

Rome is an oft-visited city, with 22.9 million visitors from January to December 2025, of whom 12 million were from outside Italy (Turismo Roma, 2026). Rome also holds over 2.7 million residents (City Population Data, 2026)

The city’s architectural, archaeological and historical importance draws vast crowds, and the city is extremely busy, noisy and frenetic, certainly not a location associated with nature or relaxation.

The public parks in central Rome are bland, with tall pines, probably Black Pine Pinus nigra, plane trees Platanus spp., Judas Tree Cercis siliquastrum, ornamental flowers and short grass, although in some areas where left uncut, native wildflowers are present, especially vetches and mallows Malva spp.

A far better option for anyone looking for nature is Parco della Caffarella, a large green area adjoining Rome (latitude 41.862697, longitude 12.520535).

The park lies about three miles from the Colosseum, about 15 minutes by car. It is walkable from the Colosseum, being on flat ground.

The park has open grassland, scrub, woodland and a small river, the Almone River. Some areas contain an intimate mixture of woodland, scrub and flower-rich grassland, and the warm, sheltered open areas were the best areas for butterflies, moths, bees and grasshoppers.

During my visit in early May, the most prominent flowers were Purple Viper’s Bugloss, Goat’s-beard Tragopogon pratensis, White Campion Silene latifolia, Milk Thistle Silybum marianum, and various clovers and wild brassicas. The plants seen being most used by butterflies were Purple Viper’s Bugloss and clovers.

I saw 21 species of butterfly in early May, including the Nettle-tree butterfly, a species that occurs mainly in southern Europe, breeding on the Nettle Tree Celtis australis, a common tree in Rome’s parks. Green Hairstreak, Common Blue, Holly Blue, and Brown Argus were seen, along with the introduced species Geranium Bronze. Red Admirals and Painted Ladies were busy breeding, with the latter breeding on mallows and thistles. Wall Browns were found in areas with bare soils and along the unvegetated tracks. A few faded Brimstones were still on the wing. Eastern Bath Whites (or Bath Whites) were also flying, and drawn mostly to wild brassicas for nectar. The Small White was very common, and the Large White was also seen, but in lower numbers.

One notable behavioural feature was the near-complete absence of butterflies before 11 am, despite the warm, calm, sunny mornings.  Some species did not appear until midday, and this includes species found in Ireland.  It is interesting to consider why most butterflies emerged later than they do in similar weather in Ireland. Have the butterflies resident in southern Europe acclimatised to require much warmer conditions to become active than those they accept in northern Europe?

The park impresses with its Nightingale populations, with beautiful singing from dense cover in various places. Blackcaps, Blackbirds, Jays, Wood Pigeons, and especially Hooded Crows, were common.

The park is large and topographically variable, with low hills and flat ground, featuring well established walkways taking you through the range of habitats present. It is a relaxing and interesting retreat from the crowds, noise and pace of Rome’s streets. Enjoy.
