crimson patch, janais patch
Chlosyne janais is a common New World butterfly in the family Nymphalidae, known as the crimson patch or janais patch. It ranges from Colombia north through Central America and Mexico to southern Texas, with occasional sightings extending into northern Texas and southeastern Mexico. The species inhabits lowland tropical to subtropical forest edges, fields, and riparian areas. Adults feed on flower nectar, while larvae feed gregariously on acanthus shrubs, particularly Anisacanthus wrightii and Odontonema callistachyus. Reproduction is continuous in the tropics; in temperate areas, multiple broods occur from July to November.
