DISTRIBUTION:

Pachygonidia hopfferi, (wingspan: males: mm; females: 74mm), flies in
Panama: Buraba (sp?); and
Costa Rica, and has been recorded as far south as
Peru: Loreto: Iquitos;
Bolivia: La Paz: Nor Yungas, Coroico, 1200m; Cochabamba: Chapare, Yunga del Espíritu Santo; and
Brazil: Parana.

Based on those locations, it should also be expected in Colombia and Ecuador.

Pachygonidia martini and P. hopfferi "can be easily separated by the form of the outer edge of the postmedian transverse band on the forewing. In P. martini it is wavy, whereas in P. hopfferi it is straight. The specimen illustrated by d'Abrera ([1987]: 109) as P. hopfferi is P. martini." Haxaire.

The forewing apex is truncated or sinuate between Rs3 and Rs4. The outer margin is concave between Rs4 and M2, and it is quite angulate at M2.

The forewing grey-brown submarginal patch on M1-M2 is indistinct, and the outer edge of the dark postmedian band is smooth.

The hindwing has three median transverse rose-pinkish bands, similar to Pachygonidia drucei. CATE

There are probably several flights throughout the year.

ECLOSION:

Larvae probably pupate in thin walled cocoons under 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:

Mature larvae probably descend host to pupate amongst leaf litter. Larvae probably feed on Doliocarpus dentatus, Doliocarpus multiflorus and Tetracera hydrophila .
