Achemon Sphinx Moth (Eumorpha achemon)
Achemon sphinx moth of the Sphingidae family is indigenous to several parts of North America. Some of the synonyms associated with this moth include Sphinx achemon described in 1777 by Drury and Sphinx crantor, coined by Cramer in 1777.
Description and Identification
The Achemon sphinx moth caterpillar is cylindrical and hairy, growing to a length of about 3 inches. Its colors vary from reddish-orange to light green to brown or tan. The younger larvae have a long and flexible spine on their abdominal tip. They have a reputation for feeding voraciously, infamous as a vineyard pest.
When fully grown, the larvae leave the vineyards, making a burrow in the soil nearby where the pupal phase starts. The pupa has a reddish-brown coloration.
Sexual Dimorphism: Present
The females appear larger than the males, also with a heavier abdomen.
