On 24th January I was in Sainsbury’s at Forestside, Belfast, Co. Down doing the weekly shop. I was well aware that oranges and lemons with leaves in GB supermarkets had been producing mines of the “snail trail” leaf mining micromoth Phyllocnistis citrella. I had searched in previous years without success. On a recent trip to Lanzarote I had found fresh mines on a lemon tree in Manrique’s garden so I was well tuned-in! My eyes were drawn to boxes of “Taste the Difference” easy-peel oranges as I could see that the fruit had sprays of leaves attached. I opened the first box and was somewhat amazed to see mines on the first leaves. In fact most boxes had the leaf mines. The mines are only in the leaf epidermis and on close inspection a thin line of black frass is visible. Fresh mines are white in appearance but after being vacated they quickly turn brown.

The oranges had been imported from Spain where this species can occur in pest proportions. Surprisingly there are no previous records of this adventive but having been alerted Ted Rolston and Andy Crory found mined leaves (and fruit) on oranges in a number of other outlets. Christmas is apparently the best time to look so you might find a welcome Xmas present if you look hard enough.

4.088 BF36a. Ectoedemia heringella (Mariani, 1939)

On 5th May 2020 Jamie O’Neill posted images on Insects & Invertebrates Ireland Facebook page of an abundant leaf miner that he found on Evergreen Oak in Phoenix Park, Dublin. He putatively identified them as E. heringella. This was quickly confirmed by Stuart Dunlop and Dave Allen (DA) who also confirmed it, after consultation with Ken Bond, as “New to Ireland”. A few weeks later Philip Strickland contacted DA with images of the same species from the same locality but taken on 13th February 2017! The mines are persistent so can be found in any month of the year. The species has obviously been established here for a number of years but remained undetected. If it follows the same pattern as in GB, where it was first found close to Kew Gardens in London, then it will certainly colonise other parts of Ireland.

On 25 August 2017 I caught an unfamiliar species of micro-moth in my moth trap at Tramore, Co. Waterford (grid reference S577013). The specimen was identified as Etiella zinckenella using Moths of Europe Vol. 4. and is new to Ireland. John Langmaid of Hampshire confirmed the identification. The moth will be lodged with the National Museum of Ireland, Natural History, Dublin.
Resident in mainland Europe, North and Sub-Saharan Africa and flying from April to September, E. zinckenella occurs as a rare immigrant elsewhere, and as an adventive species, on imported legumes. The moth was first recorded from the British Isles at Bradwell-on-Sea, Essex on 23 October 1989. Although still an uncommon immigrant to these shores it has since occurred with more frequency. The origin of the Irish specimen would appear immigrant in nature as the days immediately before and after its capture coincided with the arrival of the scarce migrants Palpita vitrealis, Delicate Mythimna vitellina and White-speck Mythimna unipuncta.

73.180 Barred Sallow Tiliacea aurago

On the morning of 11th October 2018 I (CM) inspected the moth trap as usual in my small suburban garden in Priory Park, Belfast. I deploy a Robinson trap with 125W MV bulb, which is set out on tarmac in front of the garden shed, where it is positioned to have least impact on neighbouring houses.
As I removed the lid I immediately noticed a sallow-type moth, which looked different to the pink-barred sallow Xanthia togata which is regular in the garden in small numbers. On consulting my copy of Waring and Townsend, I quickly confirmed that the moth was a barred sallow Tiliacea aurago. I subsequently found a second specimen within the trap, and having taken some photographs, I retained both specimens for further inspection.
I posted the photographs on the MothsIreland and Butterfly Conservation NI Facebook pages and it was confirmed that the species was new to Ireland.
The night of 10th/11th October was particularly warm for the time of year with a minimum temperature of 14.8C. My catch that night was otherwise typical of the time of year and included resident species such as Merveille du Jour (Moma alpium), Feathered Thorn (Colotois pennaria), Black Rustic (Aporophyla nigra) and Red-green Carpet (Chloroclysta siterata).
Barred sallow larvae feed on Beech Fagus sp. or Field Maple Acer campestre. Although neither occur in the neighbouring gardens, both species are thought to occur within Balmoral Golf Club which is across a road from the garden trap.
Having seen the moths which CM had taken, Ted Rolston (TR) decided to set out a moth trap in his garden on the night of October 12th, a few miles away at Beechdene Gardens, Lisburn. In the trap were six fresh barred sallow along with several pink-barred sallow which were rather faded in comparison. Following this, TR took a single specimen of the moth on October 15th, seven on October 20th and two on November 5th. No further specimens were taken by CM in his Priory Park garden.
The Barred Sallow appears to be spreading northwards from its original stronghold in south-eastern England and was also recorded in Scotland for the first time recently (Argyllshire 2017). Since the food plants are widespread across much of Ireland, it will be of interest to see whether the species is recorded from a wider area in autumn 2019 and beyond.

I trapped a specimen of the Box Tree Moth Cydalima perspectalis at Tramore, Co. Waterford (grid reference S577013), on 24 July 2017. The specimen was identified as a male of the brown form of the species with reference to Leraut, P., (2012. Moths of Europe 3. NAP Editions), and was new to Ireland.
A member of the Crambidae family and native to Asia it is an invasive species believed to have been introduced to Europe with imported box (Buxus spp.) of which the moth is a notorious pest with its larvae capable of defoliating the plants, Buxus sempervirens, B. microphylla and B. colchica. It is also recorded on Purple Holly (Ilex purpurea) and Japanese Spindle (Euonymus japonicus). First noted from Germany in 2007, it has since spread rapidly to many other European countries. A known strong flyer, the origin of the Tramore specimen may be immigrant in nature as its capture coincided with a spike in migrant activity. Two Diamond-back Moth Plutella xylostella, one Red Admiral Vanessa atalanta, three Rusty-dot Pearl Udea ferrugalis, three Rush Veneer Nomophila noctuella and one Silver Y Autographa gamma were also trapped, additionally, a further 23 Silver Y’s were seen nectaring at dusk.
Thanks to Ken Bond, University College, Cork and J.R. Langmaid, Southsea, Hampshire who kindly confirmed the species. The specimen will be lodged with the National Museum of Ireland, Natural History, Dublin.

On 13 August 2018, I took an unfamiliar micro-moth in a light-trap at Tramore, Co. Waterford (grid reference S577013). It was identified using the Field Guide to the Micromoths of Great Britain and Ireland as Apodia bifractella and is new to Ireland. The specimen was sent to Ken Bond who confirmed the identification. It will be lodged with the National Museum of Ireland, Natural History, Dublin.
The larva of A. bifractella feeds from mid-August to April in the seeds of Common Fleabane (Pulicaria dysenterica), Ploughman’s-spikenard (Inula conyzae) or Sea Aster (Aster tripolium), pupating from April to June, with the adults emerging during July and August. Due to the distribution of its foodplants, A. bifractella frequents a wide range of habitats including damp meadows, ditches, fens, marshes, saltmarshes, woodland rides and coastal landslips. It is found across Europe and North Africa, is widespread is southern England and is also found in N.W. England and N. Wales.

On 23 August 2017 I took an unidentified micro-moth at a moth trap at Tramore, Co. Waterford (grid reference S577013). It was tentatively identified as Eucosma tripoliana but, as it occurred away from the saltmarsh habitat of that species, it was retained and passed to Ken Bond who later dissected it and determined it to be a male Eucosma conterminana and new to Ireland. The specimen will be lodged with the National Museum of Ireland, Natural History, Dublin.
In Britain this species is reported to fly from mid-June to September and early October. It inhabits chalk grassland, quarries, gardens, waste ground and roadside verges where it feeds on Great Lettuce Lactuca virosa and Prickly Lettuce Lactuca serriola. Although the latter foodplant is a recent addition to the Irish flora and found not too distant from the site of capture it seems unlikely E. conterminana is resident here, but rather an immigrant, as the days immediately before and after its capture coincided with increased migrant activity, e.g. Etiella zinckenella taken at Tramore on 25 August 2017 was also new to Ireland. E. conterminana is recorded from southern Britain and the Channel Islands and is found from Europe to China.

Lempke’s Gold Spot – New to Ireland

Lempke’s Gold Spot from Rathlin

Lempke’s Gold Spot – First confirmed Irish records

Hazel Watson

I have been lucky enough to live on Rathlin Island for nearly three years now and, with my husband Ric Else. We have been recording moths whenever the weather allows. In this time we have managed to record 337 species, and 143 of these were new for the island’s all-time moth list, which now stands at 376 species.

Before we arrived, moth recording on Rathlin had only been very sporadic and many of those moths we’ve recorded here for the first time are relatively common and widespread species that have presumably been here all along. While it is always rewarding to add new species to the list, we had yet to discover anything of real national significance. But the morning of 23rd July 2019 was to bring us a real find, and it was one we could so easily have missed!

Lempke’s Gold Spot (left images) & and Gold Spot (right images)

That morning I had struggled to drag myself out of bed and was lagging behind the others. Still half asleep and with a mug of much-needed coffee in hand, I stumbled over to the mothing station where Ric was already getting on with the business of looking through the moth trap, assisted by a few of the keen RSPB volunteers from the cottage next door. Overnight the trap had been out in a nearby garden, where the McFauls very kindly provide excellent habitat for moths and moth-ers alike.

My eyes had barely begun to focus properly when I glanced down at a moth on an eggbox that had already been examined. In my drowsy state I could have been still dreaming, but something about the Gold Spot caught my eye. Could it possibly be….? “Isn’t that a Lempke’s Gold Spot?” I said to Ric, who surely thought I was delirious, but humoured me by having another look. We all peered closely at the moth in question. The two Gold Spot species are almost identical, but the apical streak of this one was undeniably blunt-ended – a feature of Lempke’s Gold Spot. “Surely THAT IS A LEMPKE’S!” I proclaimed triumphantly, suddenly wide awake as the penny was starting to drop that this was potentially a very exciting find. Ric had to admit it did look promising. We potted the individual for closer scrutiny later, as there were still plenty of other moths to look at in the trap. Each egg box was examined in turn, revealing a total catch of 98 individual moths of 37 species, and despite a few other goodies including our first Cloaked Minor, nobody cared much because Gold Spots were all we were interested in by this stage. In our catch we had turned up another two Gold Spots – one with typical markings and, quite unbelievably, a second that also looked a good candidate for Lempke’s. How thrilling, if this is what they really were!

Lempke’s Gold Spot (Rathlin 2019)

By this time we were running late for work, so it wasn’t until later that we could have a closer look at the two possible Lempke’s Gold Spots. Having spent the day chilling out in the fridge, both cooperated obligingly for forewing measurements, and with both at 15mm they fitted exactly within the published range for Lempke’s and at the smallest end of the range for Gold Spot (all the Gold Spots we have measured have been 16–18mm). After poring over many online images of wing markings, we felt confident that our two were consistent with Lempke’s and others who viewed our photos agreed. However, for positive identification, and as a potential national first, the specimens would have to be kept and sent away for confirmation under the microscope. As moth lovers, it is bittersweet to make an exciting find like this and have to preserve them as specimens, but it is necessary for the scientific record. We laid these two beautiful creatures to rest in the freezer, and we were delighted when Dr Ken Bond requested the specimens to be sent over from Rathlin.

We were even more delighted a few weeks later when Ken performed the dissection and confirmed that both specimens were certainly Lempke’s Gold Spots, one male and one female. He also confirmed that these would be considered the first and second verified records of the species anywhere in Ireland.

We are thrilled to have found an Irish first on Rathlin, but  we’re sure there are plenty more discoveries to be made on this exciting island.

63.002 Loxostege sticticalis – New to Ireland

63.002 Loxostege sticticalis

On Thursday 8th August 2019 I was on my usual lunchtime walk which runs along a country lane and comes to a dead end at an old basalt quarry located north of Carrickfergus in Co. Antrim, Northern Ireland.  The lands are privately owned and I am extremely privileged to have permission from the landowner to walk there.

Within the quarry there is a naturally filled pond, which is a haven for various Damselflies & Dragonflies as well as other pond creatures including Frogs and Water Boatmen.

Because the quarry has not been worked for a number of years a wide variety of wildflowers are now in abundance including Colt’s-foot, Vetches, Plantains, Knapweed, Trefoils and Meadow Vetchling to name a few.  These wildflowers not only provide nectar and pollen sources for the invertebrates but many of the plants are also important for the caterpillars of the butterfly and moth species found there.

I am a keen amateur nature photographer and I love visiting the location to photograph all the flora and fauna to be found there.  Already this year I have discovered five species of moth, which I had never encountered before.  Four species, Pyrausta purpuralis, Cydia nigricana, Capua vulgana and Lime Speck Pug Eupithecia centaureata were found within the quarry and a Vestal Rhodometra sacraria was seen on the lane leading up to it.

While I was in the quarry photographing Painted Lady butterflies which had arrived in their hundreds, I noticed something small fly past and land a few feet from me.  Being of a curious nature, I went to investigate what it was.  Luckily I was able to find it straight away and took a few photos as a record.  I knew it was some type of moth but definitely not one I had ever seen before.  I was very excited to find out what it was and couldn’t wait to get home after work to find out.

I posted the photos up onto Twitter asking for an ID and very quickly got a response back from UK Moth Identification saying that it was Loxostege sticticalis, a rare migrant species.  As anything I see usually begins with the word ‘common’, I decided to seek further confirmation and posted the photos onto the MothsIreland Group on Facebook.

Eamonn O’Donnell replied saying that it certainly looked like one and my find was better than rare.

Turns out that this is the first ever confirmed sighting of a Loxostege sticticalis in Ireland. This is a scarce migrant to Britain from Europe but has become more frequent in recent years so perhaps we can expect more to start turning up here.

So glad I decided to follow it to where it landed and investigate what it was.  You just never know what is going to turn up.

70.008 Small Dusty Wave, Idaea seriata – New to Ireland

70.008 Small Dusty Wave Idaea seriata

This is a story of an unintentional moth sighting. The evening of Friday 5th July 2019 was warm & sunny and my husband and myself decided to take advantage and go to Howth for a walk. We live in Artane, a suburban area in north Dublin. Just as I was about to get into the car, I noticed a moth on the white surroundings of our garage, so I took out the phone to pop off a picture.

When I got home post walk, I attempted to identify the moth. Well, I am a novice with moths, but I love learning what creatures are out and about in the garden, be it ants, spiders or moths. I came upon the wave (Idaea) family and saw a picture of a Small Dusty Wave Idaea seriata and thought that it looked about right for my moth. As I wasn’t sure, I turned to the MothsIreland Facebook page for some help.

Eamonn O’Donnell replied, sounding excited, but I didn’t understand why. What I hadn’t realized was that Small Dusty Wave had never previously been recorded from Ireland. Small Dusty Wave is found throughout Europe and North Africa. It is widespread in England and eastern Wales and is also found in the east of Scotland. It has also been recorded on the Isle of Man. Initially I thought it couldn’t possibly be one. What would a moth, never recorded in Ireland before, be doing on the wall of my garage? Unfortunately, by this stage, the visitor had left for its night’s adventures so I couldn’t catch it for closer investigation but, thankfully, the identification was confirmed by Steve Nash, who is familiar with the species in Britain and Dave Allen who has seen the species in France.

I have to admit I was very impressed and a little proud. It goes to show what you can find if you just look around you. I’d like to thank Dave, Eamonn, Michael O’Donnell and Steve for all the help and encouragement. It has spurred me on to start light trapping and looking all that bit closer at what is flying about.
