Libytheana carinenta also called the American snout butterfly or common snout butterfly is a member of the subfamily Libytheinae in the brush-footed butterfly family, Nymphalidae. This species is found in both North and South America. The larval host plants are Celtis species 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 this superb camouflage by hanging upside down under a twig, making them nearly invisible. Wings are patterned black-brown with white and orange markings. The forewings have a distinctive squared off, hook-like (falcate) tip.
The caterpillars appear humpbacked, having a small head, swollen first and second abdominal segments, and a last abdominal segment which 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. Their food is the common hackberry (Celtis occidentalis) tree...

GBIF citizen-science records
It is estimated from how often the American Snout is recorded against all the insects logged in Big Bend National Park (134 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
