Read the instructions...

Having been given a macro lens for my birthday, I've been re-photographing everything new in the trap. In today's last batch was a little yellow geometrid that refused to show its good side. An hour after finishing the others, and with the sun dropping in the west, I started flipping through the book to see what it might be: Spinach? Barred Yellow? Small Yellow Wave? "Dingy Shell: always rests with wings closed". WHAT!!!!

At least I worked it out before sunset, and it seems to have filled a space in the Gwent distribution map.
