Xylophanes fosteri moths [wingspan mm, females larger than males] fly in

Pupae probably wiggle to surface from subterrqnean chambers just prior to eclosion.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen. Males come in to lights very readily, but females are seldom taken in that way.

EGGS, LARVAE, PUPAE:

Larvae probably feed on Psychotria panamensis and Psychotria nervosa of the Rubiaceae family and on Pavonia guanacastensis of the Malvaceae family.

Moths emerge approximately one-two months after larvae pupate.
