Libytheinae is the nymphalid subfamily of the snout butterflies, containing two valid genera and about 10 species, 6 in Libythea and 4 in Libytheana. The common name refers to the thick labial palps (pedipalps) that look like a "snout" in this subfamily. In older literature, this group was recognized as the family Libytheidae. They are medium-sized and typically a drab brown. The front legs are reduced in length and the ventral hindwings are cryptically colored in order to help in blend in with its surroundings. While at rest, the members of this subfamily keep their wings tightly closed in order to resemble dead leaves.
