Xylophanes schwartzi (wingspan: males: 80-85mm; females: 89-95m) flies in
Ecuador, the specimen type locality.

This species is similar to Xylophanes rhodochlora in the crotonis group, but schwartzi's carmine-red wing undersides from the fw discal cell outwards and the entire hindwing clearly distinguish it.

The reddish hue manifest itself elsewhere: the inner margin of the tegulae are edged with a very narrow pink line, the underside of palps, thorax and abdomen are pale pink, and there is a thin pink line running along the dorsal surface of the inner margin from the black tuft at the wing-body juncture to the midpoint of the inner margin.

On the olive-green forewing, only the khaki fourth post median line and the small black discal dot are distinct.

The hindwing spots in the median band have a powdering of green scales in their lower quarter. The hindwing outer margin is olive-green.


Xylophanes schwartzi adults fly ????


Pupae probably wiggle to surface from subterranean chambers or leaf litter just prior to eclosion.


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.


The snake-like larva has a head and the three thoracic segments which may be retracted into abdominal segment 1, which is swollen and adorned with a pair of light-ringed eye-spots.
