?? Guatemala.

"Similar to Xylophanes aristor but smaller and forewing pattern much more contrasted. Immediately distinguishable from related species (except Xylophanes mulleri) by the partial fusion and apical pinkish flush of the pale yellow spots of the median band of the hindwing upperside.

"Tegula with a pale medial line. Upperside of abdomen with two narrow, pale lines, divided medially by a sharp, thin brown line of the same width; a black basal patch and a conspicuous longitudinal golden-yellow bands on either side of the anterior part of the abdomen.

"Outer spur of midtibia longer than inner.

Forewing upperside with first postmedian line broad and very well-marked; second postmedian line fused to first below M3; interspaces between first and third postmedian lines very pale.

"Forewing underside with apical area on costa pale buff, contrasting strongly with the orange-yellow ground colour.

"Median band of the hindwing upperside with pale yellow spots less distinct, edges suffused with orange-brown, most apical three spots more or less fused." CATE

FLIGHT TIMES:

Xylophanes eumedon 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.
