DISTRIBUTION:

Xylophanes marginalis moths fly in Brazil (specimen type locality); and
Paraguay: (possibly Misiones and Itapua (WO??);
Argentina: Misiones.

This species has been equated with Xylophanes tyndarus, but in Hawkmoths of Argentina, as per More, Kitching and Cocucci, it is treated as a distinct species.

FLIGHT TIMES:

Xylophanes marginalis adults probably brood continuously.

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 guanacastensis of the Malvaceae family.

Moths emerge approximately one-two months after larvae pupate.
