Looking at these photos I would say that the moth is Snout, they actually can be quite marked up and we had one once that was almost totally black, so variable also. That said we've had a few migrants this last week with this weather so its good to be vigilant.
Last year we had Plumed Fan-foot that my other half potted, and I almost released him before I realized it was indeed something interesting...lol
Thanks for your help with this one. I catch quite a lot of snouts here but usually fairly drab and unmarked. This one seemed out of character and with the hot weather and south-westerly breeze, thought I might have caught a migrant.
