Here we are in August, a month of grandeur for the special jewels of our landscapes. Below are some butterflies found this month, all recently photographed. What a summer we continue to have!
Common Blues are seemingly everywhere, even turning up in gardens where some are breeding. Some individual Common Blues are much smaller than they should be, no doubt products of drought conditions reducing the food available to the larvae. I peered hard at a couple today, so diminutive as to suggest a Small Blue.
Small Coppers are widespread but not numerous but this is typical of this lovely creatures population dynamic. No photograph can really represent its sparkling copper upper surfaces, so here I opt for a more sombre photograph of its undersides, still elegant and interestingly distinct from British populations. British Small Coppers usually have brown rather than grey undersides with a lesser defined, more subdued reddish hindwing band than the ones that grace our flowers.
Peacocks seem to be launching a takeover attempt at the moment. I am rarely shocked at their population sizes on good sites but the swarm encountered at a special site recently left me gaping in admiration as a blur of reds, golds and purples swirled in the sunshine! Never spray your nettles, the plant it breeds on!
The Brimstone is out in numbers now in its midland haunts, dawdling for several minutes at favoured Common Knapweed blooms, oblivious to bees jostling for their share.
Small Tortoiseshells are just beginning to show up in gardens, fields, parks and wood edges now, and will build their numbers to outnumber the Peacocks. Alas, when this happens, we know autumn is upon us!
Eden translates as delight. And this is what butterflies bring, especially to our intimate outdoor spaces. They bring personal excitement because for gardeners the boundary line between indoors and the great outdoors is blurred in the garden. The garden is a personal space, especially gardens that are secluded, private, personal havens where we can be ourselves, sometimes more than it is possible to be in the house because there we must toil. We must carry out the necessary tasks in the house. In the garden, we can choose to act or not.
In a garden to act is often to create. We can create living spaces for our fellow creatures, or choose not to. Yesterday, I spoke to a friend about his front garden. He had removed rather unkempt but Small Tortoiseshell bedecked lavenders with red-flowering begonias and a house geranium. I peered for a moment to assure myself that the new plants were not plastic.
“Why did you do that?” I queried, mystified because I know that he loved watching the tortoiseshells.
“Oh, the bees kept flying into the house”.
“You won’t have any more bees, don’t worry. What you put in here will not be touched by any bee or butterfly”.
In this case, the house has extended into the garden. The garden has become tame, a place where plants are cabinet or mantelpiece ornaments. There is little interaction now between man and nature, which has been discouraged.
Today, in many areas, butterflies are being rendered homeless. In the developed landscapes of our cities and towns as well as in the more sterilized intensively managed countryside we need to provide safe havens. Create opportunities for life to fill your garden. Butterflies can make your garden their home, with a little thought and the correct choices and actions. And there is the pleasure that grows from knowing that these butterflies, free though they are, are ‘your’ butterflies. You may even get to know individual butterflies. A kink in a wing and you know that you saw this one yesterday. Some butterflies pause for minutes but some stay for days, even weeks. One Common Blue remained in my garden for nearly a month. I said good morning to him each day until his time on earth was done. I miss him still.
Some butterflies seem to want to know you. From early July to late September each year, a small number of my garden’s Small Tortoiseshells enter my house to roost during wet weather or for the night. These stay inside for days when it is cold or raining, typically perched on a wall, ceiling or curtain until sunshine returns. Then he or she finds his or her way out through an open door or window. The occasional butterfly will roost in the house every night, leaving when it warms up the following morning. The Small Tortoiseshell is, of course, a species that passes the winter as an adult butterfly, so the individuals that come indoors regularly in autumn have already decided on their winter abode. Very occasionally, the Peacock butterfly will enter your house to stay for the winter.
Everyone knows that butterflies like nectar but not all flowers have this food. Select true species, avoid cultivars. Most lavenders contain nectar, so does Buddleia davidii, Common Knapweed, Common Marjoram, Common Fleabane, Purple Loosestrife, Water Mint, Red Clover, Common Bird’s-foot-trefoil, Devil’s-bit Scabious and Wild Angelica to name a mere handful of flowers. All easy to grow, all perennials, all sure to draw in lots of butterflies if planted in sunny, sheltered terrain. A nettle patch against a sunny hedge or wall for the Vanessids (Red Admiral, Peacock, Small Tortoiseshell, Comma) to lay their eggs on and you will have the butterflies using your garden as a breeding site too. If your hedge has Common Holly, Spindle. Common Buckthorn, Alder Buckthorn among the Common Hawthorn you will be likely to attract many moths and butterflies such as the Holly Blue.
Some ecologists scoff a little at gardens, dismissing these as poor substitutes for ‘real habitats’. This misses some crucial points. Gardens can be managed to suit butterflies in ways that many wild habitats cannot be, simply because of a lack of resources. Gardens can have a greater range of habitats crammed into small spaces than wild areas usually contain. Gardens mark the immediate interface between man and nature and being personal spaces, we are much more likely to take personal responsibility for what happens there. While gardens will never be habitats for the more localised, specialised butterflies and moths unless the gardens adjoin these habitats and might be considered part of them, a large proportion of our butterfly and moth species have been recorded in gardens. The more effectively the larger garden is managed for nature, the more attractive it becomes for butterflies and moths, and other wildlife.
Some of the rarer, more habitat specialist butterflies have been recorded in Irish gardens. These include the Brimstone, Silver-washed Fritillary, Green Hairstreak and Wall Brown. The Comma, a recent arrival still spreading from the south-east has already been spotted in Irish gardens. In the past two days, July 15th and 16th, I have seen Large Whites, Small Whites, Green-veined Whites, Small Coppers (three stubborn males bitterly contesting the same perch post on a Common Knapweed), Holly Blues, a Painted Lady, Small Tortoiseshell, Peacock, Meadow Browns and Ringlets in my garden. A few weeks ago, a Common Blue peppered the Black Medic plants pushing up through gaps in my patio stones with eggs, so I hope to see her offspring in August.
Gardens offer a great way of tracking the fortunes of our butterflies, particularly the widespread species. Get involved in our garden survey; here’s how to do this:
The hot, dry weather continues as 2018 is turning out to be a memorable, once-in-a-generation summer here in Ireland and in Britain. However, the dry conditions may pose trouble for species that breed on herbs on thin soils now affected by drought and for the grass-feeders especially those that breed on grasses in open, unshaded areas on thin and well-drained soils.
It has been a bumper year for Marsh Fritillary, now finished flying for the year. The butterfly has been expanding its distribution by taking advantage of the warmth to fly beyond the often narrow confines of its sites to seek breeding ground further afield. Another butterfly that does this is our largest native butterfly, the Silver-washed Fritillary. In early July it is at the start of its flight period and fresh examples look really magnificent so get out to the woods and look along the tracks where flowering bramble occurs. The Silver-washed Fritillary is unlikely to be missed if present. The large size, dashing yet graceful flight and deep orange upper sides marked with black bars (male only) and black spots (both sexes) make it a striking butterfly.
Avoid confusion with its slightly smaller but even faster-flying relative, the Dark Green Fritillary. The males of both species look quite similar on their upper surfaces but the undersides differ more clearly. The Silver-washed Fritillary lives up to its name by having washed silver bands on a greenish hind-wing, while silver spots on a greenish background indicate a Dark Green Fritillary. Each species preferred habitat is often different, with Dark Green Fritillary preferring more open, grassy sites but the Dark Green Fritillary may appear in large clearings in woodland and along some wood edges where the Silver-washed Fritillary flies.
The first generation of Small Tortoiseshells is flying, but most of these will not fly for long. The majority will remain on nettle beds, breeding to produce a long-lived second brood most of which will pass the winter as adult butterflies. A small number of first generation Small Tortoiseshells will not breed this year but will over-winter together with the second generation butterflies. However, some second-generation adults may breed this year to make a third brood, especially if weather conditions allow. The result of delayed breeding is that up to three generations of Small Tortoiseshells may be spending the winter as adult butterflies. The majority of over-wintering Small Tortoiseshells will be second generation adults that emerged as adults towards the end of August and during September.
Green-veined Whites will build their numbers to peak later in July, while Small Skipper and Essex Skipper butterflies are on the wing now, the latter in County Wexford where good numbers have already been seen. The new generation of Brimstones is beginning to emerge and unsurprisingly given the heat it is appearing earlier this year. Earlier emergence may mean it is active for a longer time and this will probably result in higher numbers being predated before it retires to scrub and woods to pass the winter as an adult butterfly.
Less evident but no less interesting are the larvae present now. Peacock larvae are finishing their growth and the Small Blue larvae are departing their disintegrating Kidney Vetch flowers to seek sanctuary in the substrate below. They can be seen now on good sites feeding openly on the seed on the now flimsy inflorescence. Some will be seen on stalks, heading downwards. These larvae will pass the next eight or nine months as fully-fed larvae. These will pupate from April to fly in May and June. Timing is everything for the larvae; they need to be full-grown by the time the food plant’s seed (the part of the plant the larva feeds on) falls to the soil. If not fully-fed by then, it is likely to starve. Some have probably starved already, as many Kidney Vetch plants on sand dunes have expired in the arid, rainless weeks. Expect less Small Blues next year where the plants have shrivelled.
Now follows a butterfly seen only by the fortunate or extremely dedicated searcher. The Purple Hairstreak is a tree-top dweller flying now in oak woods or woods containing oaks. However, it is very limited in its known distribution in Ireland because of the scarcity of oak woodland and woodland with good stands of oaks. Binoculars are the usual method of discerning it high up in the leafy oak tops, spinning in the sunlight in a delicious combination of purple and silver. The oak woods in County Wicklow are probably where the highest populations occur but the oak woods in Killarney National Park are reputed for its Purple Hairstreak numbers. The oaks adjacent to the American Embassador’s residence in the Pheonix Park, Dublin also has the butterfly in very good numbers.
This year Ringlets are superabundant in their favoured habitats but a concern exists for the numbers expected next year. The larvae feed on lush grasses growing in areas where some shade exists. The heat and drought, if it continues for another few weeks, may lead to a deterioration in its grasses, but these conditions are perhaps even more likely to reduce the ranks of next year’s Meadow Browns, which prefer grasses growing in open conditions bearing the full desiccating impact of hot dry weather.
However, these common butterflies will bounce back in the following seasons given the return of rain which will renew butterfly food plants. But for now, just enjoy July 2018.
This very well-attended event began against the backdrop of doubtful weather. After searing heat on Friday and Saturday, Sunday was cool, overcast and windy, not a good sign for a butterfly outing. A consoling thought was my retention of three lovely specimens caught the previous day to show at the event.
But shortly after the meeting time of 2pm, the cloud thinned and the sun shone kindly, providing a comfortable heat. A Silver-washed Fritillary, Dark Green Fritillary and a micro moth Pyrausta purpuralis were shown to great interest and appreciation from everyone there, and the fritillaries, being recent emergents, looked especially lovely.
Posing nicely for photographs, all three took to the air and off we went. The plan for the walk involved walking two adjoining but distinct habitats. The first area is mainly shattered limestone pavement with scattered scrub. This area was very disappointing. The thin soils here hold little moisture regardless of the weather conditions but the persistent heat and lack of precipitation has resulted in a starkly parched limestone grassland. The ground vegetation is largely a withered grey and straw colour, and butterflies and moths appear to have deserted the limestone. Even violet plants in semi-shade, used by the Pearl-bordered Fritillary were seen to be in the early stages of desiccation. At this stage of the summer, we could expect Common Blue, Dark Green Fritillary, Grayling, Small Heath among others here but only about five individual butterflies were seen on the limestone.
A change of scene was needed. We walked to the adjoining site which consists of deeper soil with tall grassland and scattered limestone pavement. Our luck changed with Common Blue, Small Tortoiseshell, Dark Green Fritillary, Grayling, Meadow Brown, Ringlet and Small Heath netted and shown. Marsh Fritillary eggs laid on the underside of a Devil’s-bit Scabious leaf were shown. This butterfly has finished flying and is succeeded by its larger cousin, the Dark Green Fritillary which has two large communal roosts on the site. However, a sobering reminder of life’s ephemeral beauty was afforded by the discovery of a killing ground containing the dismembered remains of dozens of the Dark Green Fritillary, as well as a Four-spotted Chaser dragonfly. A keen-eyed predator may have found the roost and if so, is exploiting this larder. It is the first time I have witnessed this concentration of dead specimens. The sight of the colourful wings arbitrarily adorning grey limestone reminds one of the final line of the poem Butterflies (by Rosita Boland): “Gaudy and ephemeral”.
One creature that appears safe from the unknown but probable avian predator is a fully-fed Narrow-bordered Bee Hawk-moth larva, which was found barreling over limestone on its way to pupate.
On a cheery note, the female Common Blues present were the blue mariscolore form, one of our loveliest butterfly sights. This occurs usually in the north and west and its occurrence in these areas may be an ecological response to a generally cooler, wetter climate. Further east where rainfall is lower the females are more inclined to have brown upper wings but in Clare blue is more prevalent.
We watched a Grayling heat up on limestone, a Small Heath patrol a patch he was compelled to share with Ringlets. We wondered would there be as many specimens of the grass-feeding butterflies here next year if the current drought continued. We will not say this too loudly, but it needs to rain!
Thanks to all who made the event so pleasurable, especially Burrenbeo Trust and to the local farmers in the area for allowing us to walk these beautiful areas.
The events were attended by Butterfly Conservation Ireland and Belfast Naturalists’ Field Club. The moth morning led by Philip Strickland was held at Lullymore Heritage Park followed by the butterfly walk led by Jesmond Harding which took place in Lullymore West and Lullybeg.
The previous night was dry, calm and warm, a perfect combination for moths. The five traps held good catches, especially the larger Robinson traps. The full species list is awaited, but highlights include Gold Swift, Goat Moth, Northern Eggar, Pebble Hook-tip, Grass Emerald, Large Emerald, Birch Mocha, Lilac Beauty, Barred Red, Waved Carpet (a scarce species), Northern Spinach, Eyed Hawk-moth, Poplar Hawk-moth, Elephant Hawk-moth, Beautiful Snout, Scarce Silver Y and Burnished Brass.
A great many photographs were taken by field club members who were very interested by the enormous range of the moths’ colours, patterns and shapes. Moth study is fascinating, even if one never gets beyond enjoying their physical appearance, especially the painstaking intricacies of their patterns.
The moths were released after the photos and their day-flying relatives were examined. A lovely female Meadow Brown showing delightfully intense orange fore-wing markings posed very nicely for the photographers. Often seen as a less glamorous species, this was certainly an arresting beauty. Ringlets bobbed along the wayside grasses following us as we made a stroll to the rich grasslands at Lullymore. Marsh Fritillary eggs were seen on the underside of a large leaf of the food plant, Devil’s-bit Scabious. These have turned purple-brown, having been laid about a week ago. Their parents are no longer alive, but have left us with the next generation in egg form.
Common Blues fluttered their shining, tinfoil blue wings above still yellow Common Bird’s-foot-trefoil flowers, while a myriad of marauding dragonflies made their direct linear flights and hairpin-bend turns. One snatched a Birch Mocha which it dispatched immediately. The species seen included Four-spotted Chaser, Black-tailed Skimmer, Brown Hawker and a single male Emperor.
Later, Dark Green Fritillaries dashed across our path and vanished as swiftly. These restless, shining orange jewels leave one breathless at their glowing colour and exhilarating movement. It is a pity, though, that they rarely allow a close view.
Near the end of the track connecting Lullymore and Lullybeg, where the two buckthorn trees grow together, a faded Brimstone arrived, still laying her eggs. We netted her for a close view to find her wings perfectly in order, after an adult life-span of over ten months. She was released and resumed her egg laying almost immediately.
There was one mystery. A large, dark butterfly was observed, fluttering around the tops of birch trees. If seen in Europe, it might be expected to reveal a Camberwell Beauty or Purple Emperor. But it did not descend, and the mystery of its identity remains.
A special thanks to the large number who attended and showed great enthusiasm for nature’s wonders. It was a lovely experience for all.
On the morning of June 22nd 2018 this lovely male Dark Green Fritillary emerged from its chrysalis low down in the vegetation on Lullybeg’s Crabtree Reserve. The butterfly is named for the green suffusion on the underside of the hind-wing. This stunning butterfly is a very powerful flyer, even in areas exposed to strong winds. Unfortunately, it is extremely difficult to approach, especially in hot weather.
The status of the Dark Green Fritillary on the Red List of Irish Butterflies 2010 is vulnerable because of a population reduction that is projected or suspected to be met in the future (up to a maximum of 100 years) based on a decline in the area of occupancy, extent of occurrence and or habitat quality. The key threats are loss of coastal habitats to erosion and golf links and a reduction in quality of remaining habitats which are suffering from the encroachment of invasive species, because these areas are no longer grazed and are left undisturbed. The encroachment of scrub on limestone, heaths and bogs is a threat to it on these habitats, as is tree planting (usually of conifers) on cutaway and cutover bogs. Destruction of limestone pavement and high quality calcareous grassland are sinister threats to this dynamic and handsome butterfly.
The species was formerly common on the cutover bog in Lullybeg. Sadly, about ten years ago it became very scarce and almost disappeared from the Lullybeg area. Steps were taken to make the habitat suitable for this magnificent species. Common Dog-violet is the main larval host-plant. The plant was largely absent from the open grassland on the reserve and the violets that exist on the reserve had become shaded by developing scrub and woodland. Heavy shade means that the violets are unsuitable for the larva. To create conditions suitable for the species, violets were planted in clumps on the open grassland. Invasive scrub with violets growing underneath was cut back manually or removed with Bord na Móna’s assistance using heavy machinery. This brought the violets back into the light. The grasses returned which provides cover and basking areas for the larva. The well developed woodland areas with violets within them were left undisturbed as this habitat is used for breeding by the Silver-washed Fritillary butterfly. The Silver-washed Fritillary also uses Common Dog-violet as the larval host-plant but its larva requires some shade for it to develop. This approach highlights the need to manage a site sensitively; actions taken to benefit a species should not damage or remove habitat for another, unless an urgent priority exists in favour of a highly endangered species. Retention and maintenance of a range of habitats is best practice especially when a large site is available for nature conservation.
The next step was to reintroduce the butterfly. A small number of adult butterflies were obtained from a large population and these were released into the habitat in 2016. Breeding was suspected in June 2017 when a female was observed on a patch of violets.
This deep orange butterfly perched on fresh green vegetation is a glorious sight on a sunny June morning, and it is heartening to see its return. Hard toil is rewarded!
Although most of our moths are night flyers, including some of our most spectacular species such as the sumptuous Elephant Hawk-moth there are some beautiful species flying now.
Here are five eye-catching day flyers. All five feed on flower nectar so you can obtain a close view of the animal. All five live in flower rich habitats and can be seen in bright sunshine.

The Narrow-bordered Bee Hawk-moth is a bee mimic and breeds on Devil’-bit Scabious. It flies in May and June. It hovers as it sups nectar from Common Bird’s-foot-trefoil, Ragged Robin and other flowers. It buzzes like a bee too but does not sting! It is often found on the same sites as the Marsh Fritillary. The lovely green and purple larvae feed singly on the host-plant and are seen from June to August.
This little moth is often initially seen as a shimmer of gleaming, iridescent green but it soon settles, usually to feed. The larvae feed on Common Sorrel but despite the abundance of the plant this moth is uncommon but widely distributed. It is sometimes seen in small numbers in a small area of high quality habitat but I usually see just a single individual. The Small Copper may also be found in the same habitats.
A highly distinctive moth both in the larval and adult states. Larvae feed communally on Groundsel and Common Ragwort, their yellow and black bands unmistakeable. Their bodies contain a cyanide compound derived from the host-plant and are avoided by birds. The moth is often abundant on vegetated sand dunes, quarries and weedy brownfield sites. While mainly a nocturnal moth, it frequently flies in the day. Its bright deep pink undersides are delightful to see in bright light, and children love their colours. However, handling it is not advised due to its toxicity.
The Six-spot Burnet is a lovely moth that can be found in vast numbers on flower rich sand dunes where its larval host-plant, Common Bird’s-foot-trefoil is abundant. In some areas there may be thousands of these moths. They fly throughout the summer.
The Narrow-bordered Five-spot Burnet looks similar to the more common Six-spot Burnet and occur together on some inland sites but the Narrow-bordered Five-spot Burnet is much less common. It was believed to be very rare but many populations have been found in the past five years, including on Butterfly Conservation Ireland’s Lullybeg Reserve. It looks slightly smaller than the Six-spot Burnet and the larvae feed on Meadow Vetchling. It seems to prefer moister habitats and flies in June and July. It visits flowers and flies in sunshine. The moth that occurs in Ireland is subspecies insularis.
We like to hear of moth records too, so please email your sightings to us, giving us the details as described under the Records Tab.
In Ireland June is the first month of summer, according to meteorologists. It is the month with the longest days, the best plant growth, the month of orchids and the peak month for butterfly species. Only a handful of butterflies do not fly in June. These are the Essex Skipper, Silver-washed Fritillary, Brown Hairstreak, Purple Hairstreak, Grayling and Hedge Brown. Every other species is on the wing and for some this month is their peak flight time.
The species that are especially notable just now are the Wood White, Green Hairstreak, Small Blue, Marsh Fritillary and Large Heath.
The Wood White, a rarity headquartered in The Burren in Counties Clare and Galway is a delicate-looking white butterfly, identical in appearance to its close relative, the Cryptic Wood White. Both are now very busy laying their eggs. The butterfly may be seen in the hazel scrub in The Burren, fluttering delicately as it searches painstakingly for the correct vetches growing in the correct positions. Last Monday I watched a female take 20 minutes to find a vetch on which to lay a single egg. When it fluttered very low it was eyed eagerly by a young frog. No wonder the Wood White is so rare! Below is a photograph of a male on Ragged Robin.
The Green Hairstreak is one of our smallest and most easily overlooked yet beautiful butterfly, sporting in bright light a shining green reminiscent of a bejeweled rain forest butterfly. It is a species of damp scrub, typically at the edge of bogs where it feeds mainly, I suspect, on Bilberry. It does have several other larval food plants but Bilberry patches in sheltered areas are the most reliable places to look for it.
Both sexes are fond of nectar, especially of the nectar of Bush Vetch. Agitate a tuft of flowering vetches, stand back and watch. A shimmer of green and dark brown (the upper surfaces are brown but the butterfly always rests with closed wings, which are green) are vaguely glimpsed while the butterfly is airborne. When settled, approach carefully for a good view. As you see from the photograph, seeing it up close is a treat.
The Small Blue is described well by its adjective but poorly by its noun. It is certainly small, but is not blue. The male only has a dusting of blue scaling near the base of the upper surfaces of the wings, the iridescence giving the butterfly a bluer appearance in flight than the settled insect has. The species is endangered and has only one food plant. The food plant occurs only on calcareous soils. It cannot withstand heavy grazing by any animal or any sheep grazing and it cannot withstand encroachment by taller vegetation. Strimming the habitat in June or July will wipe out the butterfly which feeds on the flowers only. This species is very easy to miss, but is a charming butterfly, always busy with living.
By contrast, the Marsh Fritillary is lazy. The female is especially relaxed, and perches for long periods on a leaf in the grassland, apparently doing nothing. The males are much more active, zig-zagging over the grassland habitat but even the male will sit still, especially in the mornings when he basks to warm up. The Marsh Fritillary is a lovely butterfly and in the remarkable variety of its colouring, patterning and size, one of the most interesting, with no two ever alike. The Marsh Fritillary holds the distinction of being the only legally protected species of insect in Ireland, enjoying the protection of the Habitats’ Directive 1992. This means that certain areas have been designated as Special Areas of Conservation to protect it. It is a real delight to see a fresh individual and given the fact that it is very rare in many parts of Ireland, one to keep an eye on. Its habitat must be maintained if it is to continue to survive.
The Large Heath will not win any design awards. It is one of our dowdier butterflies, with some specimens looking fairly grey on the wing but it is dying out with the annihilation of its wet bog habitat. One of our most sensitive butterflies, it is in trouble here and in Europe. Because very few people tramp across the tricky ground of wet bogs, it is rarely recorded but it’s out now, so take a look at him while you still can. Think of this bog butterfly’s needs the next time you’re about to throw turf on the fire or garden using peat.
A final and really delightful butterfly is the Small Copper, aptly named. Rarely seen in number, it is a special experience to see a pristine example, like the females below, feeding on a buttercup.
Enjoy the photographs, but get out in good habitats and look for the real thing!
A breezy, mild day with occasional sunny spells gave the weather context for our annual outing to the wonderfully rich habitats in the wilds of Lullymore and Lullybeg.
One of the great pluses of the area is the that there is no long trek to locate the areas treasures, no difficult terrain to tackle, no dull areas to traverse to reach the good spots. The entire area from the parking point to the western limits of Butterfly Conservation Ireland’s reserve offers abunance to the wildlife lover.
Right beside our parking point a rarity was pointed out by Philip Strickland, our moth specialist. A lovely White-pinion Spotted moth, perched serenely on a birch leaf, its snowy white standing out sharply on dark green. There are no other midland records for this moth! You can see photographs of it on our Facebook page.
Cryptic Wood Whites fluttered gently along the track ahead, looking delicate and ethereal. This dainty sylph floats about the solid world of tangled grasses and scrub, searching almost abstractedly for a mate, nectar or a place to perch or lay an egg.
A sharp contrast to the dreamlike sensation evoked by the ghostly wood whites is the hyperactivity of the Dingy Skippers and Burnet Companions. These don’t stop when the sun is out,buzzing excitedly around inky milkwort and cheery yellow bird’s-foot trefoil, chasing and supping nectar. Mating was observed; a quiescent female folded her wings and allowed joining. Earlier, another disdainful female raised her abdomen towards an amorous male in the classic rejection posture. The ever-interesting Narrow-bordered Bee Hawkmoth was surging across the grassland, while a more ponderous female was observed inspecting the vegetation for egg-sites. This bumble-bee mimic not only imitates a bee’s appearance, it makes a loud buzzing sound too.
Brimstones are still about too, but these showy butterflies are currently being gobbled by Hairy Hawker dragonflies which assassinated five on the track alone! Beautiful dragonflies they are, but also ferocious killers. Peacocks are still extant, and apparently not as vulnerable.
The star of the show was the Marsh Fritillary, just beginning to fly at Lullymore and Lullybeg. Only males were seen, all pristine. There will, given sunshine, be many more in the weeks again, but no two look alike, adding endless intrigue to the study of this iconic butterfly.
Thanks to everyone who joined us. It was great to have your company, and share the beautiful butterflies of Kildare’s best butterfly site.

After a long, dark winter and wet, cold spring there has been some nice activity over the past two weeks. The Orange-tip has finally broken its silence and is tremulously flashing his fresh orange painted forewings across the countryside canvas. He took his time, held back by forbidding cold. He is a welcome sight.
The humbler, dainty Green-veined White is now occupying the same wood clearings, tree-lines, hedge-banks and wetlands as the Orange-tip. The two species often use different parts of the same food plant, Cuckoo-flower to avoid dangerous competition. The Small White has been sighted too but the second generation in summer is when the highest numbers are seen.
The Peacock, Small Tortoiseshell, Brimstone and Comma were first out. These over-winter as fully developed adults so have a head-start on everyone else. They all have the crucial advantage of longevity so can wait for their larval food plants to be ready. The Brimstone, for example, waits around two weeks after mating to lay her eggs and she will continue to lay until well into June or even early July.
Red Admiral and Painted Lady butterflies are migrants and can appear at almost any time of the year. Small numbers are recorded so far. The bigger numbers usually begin in summer.
The lovely Holly Blue is out in sunny, sheltered areas from Donegal to Dublin. The main spring flight is usually in May but March records occur in early warm springs, but not this year. The tiny Green Hairstreak has been sighted in out of the way places such as bog edges and wet heaths beloved of this beautiful creature.
Finally, the Speckled Wood has emerged but in very small numbers so far. A fiercely territorial male will beat off any other male who tries to muscle in on his warm, sunny patch of hedgerow or wood edge. Battles involving tight spirals are often seen on country roads from April to October.
In May look for Wall Brown, Dingy Skipper, Large White, Cryptic Wood White, Common Blue and Marsh Fritillary. In the Burren, look for our greatest rarities, the Pearl-bordered Fritillary and Wood White. These two species will fly together, in herb-rich areas of open scrub. And remember to send in your records to us by email to firstname.lastname@example.org. See Records tab first!
