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).

Leptotes cassius

Leptotes cassius, the Cassius blue or tropical striped blue, is a butterfly of the family Lycaenidae. It is found in North America in Florida including the Keys, Texas south through the Caribbean, Mexico, and Central America to South America. Strays have been found in New Mexico, Kansas, Missouri, South Carolina, North Carolina and Virginia.[2]

The wingspan is 20–35 mm.

The butterfly species has an important role in Marisha Pessl's 2006 novel Special Topics in Calamity Physics. The protagonist, Blue van Meer, is named in honor of the Cassius blue.

The caterpillars feed natively on Fabaceae. Food plants on record are Amorpha crenulata, woolly rattlepod (Crotalaria incana), Galactia regularis and lima bean (Phaseolus lunatus). It can also successfully develop feeding on Cape leadwort (Plumbago auriculata) or doctorbush (P. scandens), which (among the eudicots) are not closely related to its usual food plants.[3]

Subspecies

  • L. c. cassius – Suriname
  • L. c. catilina
  • L. c. theonus (Lucas, 1857) – Florida, Cuba, Bahamas, Greater Antilles
  • L. c. cassidula (Boisduval, 1870)[4] – Texas, Mexico, Honduras to Panama
  • L. c. cassioides – Windward Islands, including Dominica and Trinidad & Tobago
  • L. c. striata

L. c. theonus (and consequently L. cassius itself) is the type species of the genus Leptotes.
