Erebus ephesperis

This large moth looks like a dead leaf. When disturbed it flies a few metres and immediately settles at the base of a tree or among dead leaves. Despite its size (around 70mm wingspan), it is surprisingly difficult to spot. At first I thought that the forewings were damaged, but it’s actually part of the pattern! It’s remarkable how the pattern includes a “shadow” effect, making it look like a ragged edge.(see more pictures here)
