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.

Two eagle eyed girls spotted a large caterpillar which had fallen out of a Lime tree in Dublin.

This was identified as Lime Hawk-moth and photos were forwarded to MothsIreland for confirmation. The blue horn, the warts on the anal flap and the green head with white stripes are diagnostic. This is the 3rd Irish record. The 2 previous records were both adults and both also north Dublin City.

The first Irish record was in 2010 in Drumcondra. It was not known if it was of local origin or perhaps flew in from Britain where it is well established in southern England.

The case that it is resident became much stronger with the 2nd Irish re

cord of an adult that came to light earlier this year in Baldoyle. There’s no question about its residency now!

The species has been spreading northwards in England and so perhaps it will be seen away from north Dublin soon. It isn’t restricted to Lime. Birch and Alder regularly host the species and other tree species may be used as well.

Maybe you’ve seen either the caterpillar or adult, but didn’t know what it was or know of the significance? We’d like to hear about it.
