Synonyms and other taxonomic changes
Libytheana carinenta (Cramer, 1777)
Syn: Libytheana bachmanii (Kirtland, 1851)
Snouts are sometimes placed in their own family, Libytheidae, as the larvae lack the spines and horns of most Nymphalidae and the pupae lack the dorsal bumps of most Nymphalinae.
Explanation of Names
"Snout" name due to extended labial palps.
About eight species occur throughout the tropical and subtropical regions of the world.
41-51mm (1)
Beak-like labial palps. Topside forewing has white spots and orange patches on dark background. Underside violet-gray. (1)

Resident in southern U.S. and Mexico. Periodic to northern U.S. and extreme southern Ontario.
Gilbert's (1985) review of published accounts of snout migrations in south Texas between 1912 and 1980 found that migrations occur from late June to mid-October.
Hackberries (Celtis) and sugarberry. (1)
primarily, Spiny Hackberry ([url=]Celtis ehrenbergiana (=pallida)) across south Texas
Only snout butterfly that occurs regularly north of Mexico. (2)
Raymond Neck (1983) was the first to note that snout population size is positively correlated with the intensity and duration of dry periods immediately preceding drought-terminating rains. Larry Gilbert (1985) conducted the most intensive study yet of snout population explosions in south Texas.
