Adam Lazarus sends in an utterly pedestrian photo of a Japanese moth resting on a wall:

But wait! Have a closer look:

Incredible!

A predatory bird aiming at an apparent moth body will find little more than the empty space between the butterfly’s hindwings, giving our upside-down trickster a chance to escape.

As best I can tell this is a common mapwing, Cyrestis thyodamas. I’m not a Lepidopterist though, so take this ID with a grain of salt.
