Other than thinking this is a Tortrix I am a bit stumped!
This is a side view of the above.
I can see a number of possibilities for this including Grey or Light Grey Tortrix, but again not sure.
I think this may be a Tawny Marbled Minor. 3 of these arrived last night, all with a distinctly different colouration (a greeny bronze which is lost in the photo) from the Marbled Minors that I have been seeing recently. Certainly it is the right size.
Again, not sure, but possibly a Caloptilia?
If anyone can shed any light on these, I would be very grateful!
