Inspired by the mild weather, I put the trap out last night in a wooded area, which I was sure would be an improvement on the three moths in my garden trap (Hebrew Character, Common Quakerx2) the previous night. It wasn't.
Only one, rather small, moth. I potted it anyway, had breakfast, went to the supermarket, and then took a photograph. It turns out to be a new species for me, Agonopterix alstroemeriana, which the book says is Common. There's certainly plenty of the food plant around, but the county list suggests that's it's only the fourth Ceredigion record. Happy New Year!
