New to Ireland

63.014 Sitochroa Palealis – First Irish record.

It was 17th July, and I was on my holidays at a place called Ballyconnery, approximately 7 kilometres north of Dungarvan, Waterford. My uncle Philip arrived down with a car full of moth traps and we set out to put several 125w Robinson’s MV traps in various locations around the house and farmland where we were staying. The habitat looked really good for trapping with a mixture of scrub, native meadow and mixed woodland nearby. Three traps were set up in the fields and scrub and were powered using a string of 50m mains extension cables thereby allowing us decent coverage. One was comfortably nestled at the front of the house among a mixed wildflower and Verbascum garden (no sign of any mullein moth activities unfortunately).

The week had been a hot one and the next was to be even hotter. Temperatures for the night reached a low of around 16-19 degrees Celsius and as day became night, the traps began to light up. Things were already looking good, and it was about to get even better. During the night, we checked the traps to see if any interesting species had entered. An obvious and striking record to be noted was the Orange Moth Angerona prunaria.

The sun rose early that morning, as it does in July, and we set off to inspect the traps just as it was rising. When going through the contents of the third trap, we came across what seemed to be a relatively large and pale micro-moth. I could only think of it as being an unusually large Timothy Tortrix Aphelia paleana. It was sitting in a part of the trap that made it difficult to pot and during its attempted capture it flew up and away before circling around and eventually landing on my T shirt! Luck was with us, and Philip made sure to seal the jar firmly, preventing any further calamity. 

The fourth trap was done thoroughly and with a sense of great anticipation at this mysterious moth’s identification. The process began immediately after any necessary clean-up. We made certain of the confirmation that it was indeed not a large Timothy Tortrix but after a brief additional surfing through multiple picture and photograph books, both of us were in agreement. The moth could only to be Sitochroa palealis, a moth previously unrecorded in Ireland. 

The moth was pale with dark vein-like patterns, living up to its description as “pale sulphur yellow to whitish…veins variably darker.” (Sterling and Parsons, 2012) It had an obscure dark spot as also mentioned in the book. The specimen was retained to ensure any further analysis could be done if needed. 

Sitochroa palealis is found throughout mainland Europe and also in the south of England. Its vernacular name is the Carrot Seed Moth as the larvae feed on wild carrot and similar plants. It is a species of the family Crambidae with a wingspan of 26–34 mm.

A combination of great habitat, perfect trapping conditions and the right time of year resulted in a very productive night’s trapping with approximately 150 species recorded. Other notable records included Cloaked Pug Euphyia biangulata, Pammenne regiana and Hedya ochroleucana.

Phyllonorycter tristrigella – New to Ireland!

15.078 Phyllonorycter tristrigella (Haworth, 1828)

16th August 2022, Minnowburn, Belfast. Off on my regular morning jaunt with our dog, Milou we ended up by the Minnowburn stream where there is good tree cover including a couple of Wych Elms Ulmus glabra in the under-storey. I initially noticed a gallery mine (turned out to be Stigmella lemniscella – yellow larva present) but then to my astonishment a tentiform mine of a Phyllonorycter, something I had never previously seen on Wych Elm, caught my eye. There are only two options in GB noted on the leaf mining websites, P. tristrigella and P. schreberella. There are no cross-over species listed i.e. species on the “wrong” host. A quick run through the keys and checking images quickly confirmed the mine to be P tristrigella. P. schreberella forms an oval tent/blotch, often crossing veins, it is uncommon on Wych Elm and has a very southern distribution in GB. Tristrigella mines lie between veins forming a strongly contracted tube running from mid-rib to leaf edge, obvious in the attached images. There are a few strong folds on this mine which hard to capture in the image as the mine is so puckered causing them to merge. Frass was tightly packed in bottom corner of the mine. The mine was vacated. Amazingly following this discovery Eamonn O’Donnell found a long vacated mine, also on Wych Elm, in Dublin the following day!  Thanks again to CEDaR and the Environmental Recorders Group small grant. To date I have found it nowhere else despite searching.

4.074 Etainia sericopeza (Zeller, 1839) – New to Ireland

Thanks to a small grant from CEDaR Environmental Recorders Group I was to spend a bit more time than usual looking at leaf mines in Northern Ireland. One of my search areas, which I have rarely visited, was Ormeau Park, Belfast (Co Down) not very distant, but an area with many mature trees and a good under-storey.

A gentle stroll into the park on 22nd July 2022 quickly revealed a number of common species on beech and hazel. A mature Norway maple (Acer platanoides) then drew my attention. In Ireland I have been looking in vain for “samara miners” for over six years. I have seen two species with ease in France so my eye is “in”.  A number of samaras were on the ground, I was totally flabbergasted to immediately find two mined samaras. The mines were of Etainia sericopeza (field maple and sycamore have different miners).

The egg is laid on the wing of the samara, the larva then mines a thin gallery towards and into the seed. Depending on the age of the samara the mines can be obvious or more cryptic.

On 23rd July I could not believe my luck in finding another mined samara, this time at Shaw’s Bridge, Belfast (Co Antrim).

4.057 Stigmella suberivora (Stainton, 1869) New to Ireland

Thanks to a small grant from National Parks and Wildlife Service I was able to survey leaf mining Lepidoptera in the Republic of Ireland. Although my focus was on the border counties where leaf miners are seriously under recorded I kept the brief broad. This allowed me to travel to Meath and Dublin where I teamed up with my old friend Eamonn O’Donnell and his partner Kerri Gorentz. One of our search areas was to be the Botanic Gardens and Cemetery at Glasnevin, Co Dublin. These places are usually good for leaf miners with an array of exotic, non-native trees and shrubs. I was also well aware of the recent discovery of Ectoedemia heringella on evergreen oaks Quercus ilex at the Botanic Gardens.

E. heringella was easily found in both the Gardens and cemetery. Typically, it is already abundant with multiple mines on many leaves. I knew from looking at leaf mines in France and London that another species could also occur on these trees, S. suberivora, but that finding it has become much harder because of the density of heringella mines which can obscure it.

After about fifteen minutes of searching I found what I believed to be two mines of suberivora. Both were on leaves lacking heringella mines. The heringella mines are small ad compact taking up on average less than a square cm whereas the two suberivora mines were long (just over 4cm) and along the leaf margin. Mines of both were packed with black frass and egg upper in both cases. Without backlighting the mines are buffish in colour. As heringella increases in numbers, which it will, then suberivora is likely to become increasingly difficult to locate. A number of UK experts concurred with the identification.

73.330 Radford’s Flame Shoulder, Ochropleura leucogaster – New to Ireland

On arrival at Cape Clear Island, West Cork in October 2021 for my usual sojourn, it quickly became obvious that there were quite a few migrant moths and Red Admirals about. There were a few Rush Veneers Nomophila noctuella and uncountable numbers of Rusty-dot Pearl Udea ferrugalis seen throughout the island each day. The weather was generally drifting South/South-east all week and with mild nights my trap was put out most nights mostly because of the unending enthusiasm of James McNally.

During the week in a discussion with Michael O’Donnell he happened to mention that there was a large number of Radford’s Flame Shoulders Ochropleura leucogaster in Britain and that I should keep an eye out for it as it is a migrant species. We, James, Dr. Geoff Oliver and I, were a bit disappointed by the quantity and quality of what was in our trap most night with lots of Rusty-dot Pearl and on one night five Gem Orthonama obstipata being the only moths of note. Later that week we trapped a Flame Shoulder Ochropleura plecta, which is the only possible confusion species with Radford’s but as I am very familiar with this common species there was no sense of excitement.

However, on emptying the trap on the morning of the 16th, Chick (JMcN) took out an eggbox with just one moth on it and I quickly noticed it was similar to but different from Flame Shoulder. Could it be? I quickly potted it for closer examination and was pretty sure that what I was looking at was a Radford’s Flame Shoulder. The moth was longer and narrower than Flame Shoulder and the white edge to the wing reached the ‘shoulders’ and continued across the thorax to complete a white-lined loop. This feature is not mentioned in the literature but is very obviously different to Flame Shoulder. I was able to see that the moth had pure white hindwings which differ to the yellowish hindwing of Flame Shoulder. I was sure that we were looking at a first Irish record and this was quickly confirmed on a UK moths Facebook page.

This was the first but will not be the last. Of that I am certain.
