Yellow shell moth (Camptogramma bilineata)

I was scanning the birch sapling this evening and what appeared to be a dead leaf turned into a yellow shell moth. Though a new record for the project, this is a common species whose caterpillars feed on docks, chickweed and other low-growing plants, so it may have grown up in Emthree.

The yellow birch leaves have been attacked the microfungus Asteroma microspermum and, as the top picture shows, the moth has quite a good resemblance to these and is easily overlooked.
