Leptotes cassius
Cassius blue, tropical striped blue
Leptotes cassius is a small, strikingly blue butterfly in the family Lycaenidae, distributed across the southern United States, Caribbean, Mexico, Central America, and South America. The species exhibits facultative myrmecophily, with larvae tended by Camponotus ants, though ant presence does not significantly influence oviposition decisions. Caterpillars are florivorous, developing inside flower buds of leguminous host plants. Multiple subspecies are recognized, with L. c. theonus serving as the type species of the genus Leptotes.
