About the Tetrio Sphinx

Pseudosphinx is a monotypic genus of moth in the family Sphingidae first described by Hermann Burmeister in 1856. Its only species, Pseudosphinx tetrio, was first described by Carl Linnaeus in 1771. Its common names include tetrio sphinx, giant gray sphinx, frangipani hornworm, and plumeria caterpillar. In the island of Martinique it is best known as Rasta caterpillar (chenille rasta, in French) because of its colors which are reminiscent of the ones found in Rastafarian clothing and accessories. It is native to the tropical and subtropical Americas from the southern and southwestern United States to Brazil. The occasional individual has been recorded as far north as the northeastern United States.

The adult moth is brown with gray and white markings, and the hindwing is a darker brown. The female may be lighter in tone. The body has gray, white, and black bands. The wingspan is 12.7 to 14 centimeters, and the female is generally slightly larger than the male.

The larva is a caterpillar which may exceed 15 centimeters in length. It is black with aposematic yellow bands and a red-orange head. Toward the posterior end is an orange bump with a black horn roughly 2 centimeters... Wikipedia →
