High Quality Content by WIKIPEDIA articles! Charaxinae, the leafwings, is a nymphalid subfamily of butterflies that includes about 400 species, inhabiting mainly the tropics, although some species extend into temperate regions in North America, Europe, China and southern Australia. There are significant variations between the species. For example, some are medium-sized and bright orange above, but mottled gray or brown below. This underwing coloration helps them resemble a dead leaf when they are at rest as they keep their wings closed. With relatively few exceptions, the hindwings of the members of this subfamily have jagged edges.
