FLIGHT TIMES:

Enyo gorgon gorgon probably has two to three broods annually, with adults taken in Costa Rica from May to June, August to September and from December to January.

In Bolivia, specimens have been recorded in October-November. Johan van't Bosch reports an August flight in Mato Grosso, Brazil.

Early evening, just prior to 7:00 pm seems to be a popular flight time response to lights in Bolivia with both males and females coming to lights.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen. Both males and females nectar at flowers. Females, active from 12:30 - 2:00 pm, are seldom taken at lights while males, active from 1:00 - 3:00 am, are more common.

EGGS, LARVAE, PUPAE:

Larvae feed on Vitus tiliifolia and other members of the Vitaceae family.

The "horn" is very long in early instars and head is relatively large.

Larvae also feed on Tetracera volubilis of the Dilleniaceae family. The "horn" is quite diminished in the final instar and now the head is small compared to body girth.

Eclosion from pupa is about four weeks after pupation. The pupa is dark and smooth with a long, sharp cremaster.
