A Large Nosed American Snout Butterfly

American snout butterfly photographed at White Tank Moutain Regional Park, AZ

When you first see an American Snout butterfly you stare at that shnoz! After a moment that thought is forgotten and that’s it, you’ve seen your first American Snout.

This one is busy nectaring in its home habitat, the White Tank Mountains just west of Phoenix. They are found throughout much of the US, though.

A quick flyer, Libytheana bachmanii flee when you approach, but go only a short distance. That’s a boon to observing and photographing them.

Look closely and you’ll see the rich colors of their wings.

  1. The American Snout or Common Snout Butterfly (Libytheana carinenta) is a member of the Libytheinae subfamily, in the brush-footed butterfly family Nymphalidae. This species is found in both North and South America. The larval host plants are Celtis spp. on which the eggs are laid singly. Massive migrations of this species often attract attention in the Texas and Mexican newspapers.

    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.
