DISTRIBUTION:

Madoryx bubastus bubastus (wingspan: 92-120mm, males considerably smaller than females) flies in Central and South America;
French Guiana;
Guyana: Berbice; and
Venezuela: Aroa;
Ecuador;
Bolivia: Santa Cruz (750m);
Brazil: southern Maranhao;
Paraguay: Cordillera; Guaira; and
Argentina: Misiones (100m). Dan Janzen confirms it from Costa Rica, and
Jose Monzon confirms it from Guatemala

It flies as subspecies M. b. butleri in Mexico, Guatemala and Belize, and then probably as the nominate subspecies throughout the rest of Central America and into South America, probably as far south as Paraguay: Central: San Lorenzo (PS).

I see no reason why it would not be found in Nicaragua, Panama, Colombia and Peru.

The uppersides of the body and wings are more-or-less olive-brown. The forewing apex is truncate. The upper silver discal spot on the forewing is small, and can be rounded or ovate. The lower silver spot is irregularly triangular, with its upper inner edge directed towards the costa.

A very acute angle is formed by two pales lines near the end of Rs4, the outer line ending at the tip of CuA1, and the inner line ending near the midpoint of the inner margin. The area bounded by these lines is dark. A broadly preapical, pale line, emanating from the costa, meets the pm line at an internal angle of slightly less than ninety degrees.

There are two dark brown spots, the smaller capping the larger, along the inner margin halfway between the pm line and the anal angle.

FLIGHT TIMES:

Moths are probably on the wing in just about every month.

ECLOSION:

Adults eclose, usually within three weeks, from pupae formed in flimsy cocoons spun amongst leaf litter.

SCENTING AND MATING:

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

EGGS, LARVAE, PUPAE:

Larvae feed on Guettarda macrosperma and spin a very flimsy cocoon amongst leaf litter.
