Epipleminae

The Epipleminae or epiplemiine moths are a subfamily of the lepidopteran family Uraniidae. They are the most diverse and widespread uraniid group, occurring mainly throughout the Pantropics but barely reaching into the temperate regions. The Epipleminae are notable for the sexually dimorphic tympanal organ which is unlike any other butterfly's in details of its morphology. Some species are also peculiar in being able to rolling their wings into a stick-like shape, possibly as a form of crypsis. Such behavior has hitherto only been found in this subfamily and the quite unrelated Ennominae.(Sohn & Yen 2005)
