Rick Gillmore reports, "A. fadus does not exist in Florida. They are not breeding here in Florida."

This species is easily confused with other Aellopos species and some citings may be in error.

Macroglossum annulosum Swainson, 1882, Brazil, is same as Aellopos fadus
Macroglossa annulosum Balteata, Kirtland, 1851, Ohio, is same as Aellopos fadus
Sesia f. flavosignata Closs, 1916, Brazil, is same as Aellopos fadus

The body is brown with a wide white band across the abdomen. The upperside of wings is dark brown; the forewing has two bands of pale spots and lacks a black spot (typical of clavipes) at the end of the cell; the hindwing has a pale patch on the costa and one on the inner margin. Note the double line of white spots in the forewing postmedian area.

In Costa Rica moths have been taken in all months except March and September to November. The moth broods continuously in the tropics.

In Texas, Arkansas and Florida there is one flight from September-December. Adults nectar on flowers, including Abelia.


Adults eclose from pupae formed in shallow subterranean chambers.

Females call in the males with a pheromone released from a gland at the tip of the abdomen.


Larvae feed on various species of the Rubiaceae (madder) family, including Genipa americana and Alibertia edulis. and Randia species.

There are at least two color morphs, a green form and a much darker, reddish-brown form:

Caterpillars pupate in loose cocoons in shallow underground chambers.

Pupae are dark, smooth and shiny, and relatively thin considering the stout appearance of the moth.
