Xylophanes juanita moths
(wingspan 57-59 mm) fly from Mexico
(specimen type locality) and Belize to Costa Rica.
Xylophanes juanita adults probably brood continuously with pupae emerging after rains.
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 horizontalis, Psychotria correae,
Psychotria microdon and Psychotria nervosa
of the Rubiaceae family.
The false eye is divided into two parts, and this features is very
distinctive of this species. There are several colour morphs. In one morph the last instar has yellow eyes and a
blue/green body, side slashes.
Moths emerge approximately two months after larvae pupate, but some that pupate in July don't
emerge until December or even March. Pupa has a spatulate tip as opposed to a sharp cremaster.
Larvae are subject to parasitization by Drino sp. 6of the Tachinidae family.
