A caddis fly which came to a light left on overnight. The wing patterning suggests Anabolia nervosa.
Edit: Changed to match nightfly's ID. Many thanks.
No interactions present.
This one reminds me of an observation of a caddisfly about 2 years ago- feels like that much anyway. It was difficult to tell if it was Anabolia or Potamophylax. This one looks like the latter to me at this stage but I'm not certain about it. Ive only refered to a couple of A. nervosa images since you posted this one, I cant see pale apical cell dashes in the couple Ive looked at, possibly no hairs on top of A. nervosa?
I based my ID largely on the photos at http://www.naturespot.org.uk/species/anabolia-nervosa ... which may, of course, be wrong!
Firstly, I think Ive called you Malcolm in a recent comment, sorry I now realise (again) that thats your surname.
I think your caddis is a Potamophylax as the rear end of the forewings arent pointed enough for Anabolia nervosa and and those pale dashes in the apical cells are typical of Potamophylax but not present on Anabolias I have viewed so far. I got one last night which is the same as your one as far as I can see:-
I've been called much worse!
I think you've convinced me about Potamophylax: I'll change the title.
