A lovely moth that perched on standard lamp in garden wingspan. 40mm
No interactions present.
Hi Foxy, this certainly looks like Pale Oak Beauty to me. The only reason I hesitate to confirm it is that according to the information I have to hand, there is only one previous Irish record, from 1914! I'll ask Angus Tyner of the Moths Ireland project (http://www.mothsireland.com/index.htm) to have a look. If you still have the moth he might be interested to see it.
Entomologist and biological recorder
After discussion with Angus Tyner, plus a view of a second photo of the same moth, I now think that this is an Engrailed, rather than a Pale Oak Beauty. Normally these two species are reasonably distinct in size and markings, but both are variable.
Sorry for getting your hopes up on this one! If you see any more do post the photos.
the only reason I said Pale oak beauty was that I could not match it to any engrailed in Waring and Townsend and it looked very like pale oak beauty as pictured in Chris Manleys British Moths (page 164) I was not aware that it was not found in Ireland in the last 90-100 years but not much recording has been done in this area.
I will post second photo so others can compare same ,
