The Asteroid
Cucullia asteroides
September 20, 2003
Great name for a moth - Asteroid! And fitting, too. Even when sitting still it looks like it's rocketing through the air.
The pattern and color, however, actually serve to make it look like a piece of tree bark. An aerodynamically streamlined piece of bark, but I suppose that's just to the human eye (mine at least).
