Thanks to Tony and George for the help with the ID.
I'm surprised that there are no further comments. Possibly we are all stifled by envy. What a lovely moth, it must have been a real thrill to find it. Is it common anywhere?
Thanks for your kind words, David. There had already been various communications by email before I was asked to post it here and many comments had already been made off-blog.
Yes it is common in the South. The Bucks database has 623 records for example. Presumably this one strayed up from Carmarthen.
I think they have been recorded regularly in Pembrokeshire, so it may have travelled a little way up the coast. Lets hope it breeds and then spreads up the Ceredigion coast.
Large Ranunculus is regular on the S Carms coast around Llanelli and I used to catch it regularly when I lived in Milford Haven. I guess it may be spreading north and your Aberporth one could be the vanguard of colonisation. L-album Wainscot next...?
Congratulations on earning a green cross on the VC46 distribution map and a new dot that will appear in the new Atlas. There is one dot in the present Atlas just south of VC46 so there is hope.
