DISTRIBUTION: Xylophanes guianensis moths fly in Guiana (specimen type locality) and southwest to Bolivia: Santa Cruz: Ichilo, El Chore. Xylophanes guianensis moths rest with wings closed, revealing streamlined head, thorax and abdomen.

The two outer lines run parallel to the median line along the entire length of the abdomen, whereas in X. ceratomioides, the outer lines converge towards the anterior margin of each abdominal segment, giving a chevroned appearance.

FLIGHT TIMES:

Xylophanes guianensis adults probably fly as multiple broods.

ECLOSION:

Pupae probably wiggle to surface from subterranean 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 guanacastensisof the Malvaceae family.

Moths emerge approximately one-two months after larvae pupate.
