North American Ecology (US and Canada)

Leptotes cassius ranges from Argentina and throughout the Antilles north to the United States. It is resident in southern Texas and Southern Florida and migratory northward into the central US, possibly occasionally as far north as Iowa and Utah (Scott 1986). Habitats are subtropical open areas and woods edges. Host plants are usually herbaceous and include species from many families. Eggs are laid on the host plant flowers singly. Larvae are associated with ants. There are many flights all year (Scott 1986).
