I believe this is the peppered moth - Biston betularia - which many will remember from biology classes, where it was held up as an example of evolution in action from the all-black phase which became prevalent in sooty, industrial parts of britain.
It normally lies with its wings flat against a black and white, textured surface where it can be very hard to spot. The unusual pose here might indicate that this is a newly hatched moth that is still inflating and hardening its wings.
