Yellow Shell

Yellow Shell, Camptogramma bilineata.  Geometer.  Moth trap in Hayes, on 4 September 2011.

One of the interesting things about my moth trap is that I catch things I never normally see. This Yellow Shell is common, according to the books, and I suppose it's because it flies by night that I have never seen one before.

It is standing on an egg-box, one of those that are put in the trap to provide hollows and nooks for the moths to rest in, and it's just about to take off — like the Common Carpet I showed on 11 September. This looks a lot more dramatic than the usual resting position.
