Snout butterfly

The American or Common Snout Butterfly is a member of the Libytheinae subfamily, now placed in the brush-footed butterfly family Nymphalidae, formerly a distinct family. It usually includes the taxa formerly separated as Libytheana bachmanii nowadays, but this is not universally accepted.

Snout butterflies have prominent elongated mouthparts (labial palpi) which, in concert with the antennae, give the appearance of the petiole (stem) of a dead leaf. Snouts often take advantage of their brilliant camouflage by hanging upsidedown under a twig, making them nearly invisible. Wings are patterned black-brown with white and orange markings. The fore wings have a distinctive squared off, hook-like (falcate) tip. Caterpillars appear humpbacked, having a small head, swollen first and second abdominal segments, and a last abdominal segment that is tapered and rounded. They are dark green with yellow stripes along the top and sides of the body, and have two black tubercles on the top of the thorax.
