FLIGHT TIMES:

There are several flights throughout the year in the tropics with moths predominantly on the wing at dusk.

In northeastern Argentina (Misiones Province) there is at least one flight in December (Oz Rittner). Larry Valentine confirms May and January flights in Itanhandu, Minas Gerais, Brazil. Andres Urbas reports an April 1, 2011, flight near Kaw, French Guiana. Gregory Nielsen reports a June flight in Meta, Colombia. Brain Fletcher reports an October flight in Costa Rica.

SCENTING AND MATING:

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

The outer margin of the male forewing is almost straight, while in females it is quite convex. This species seems mots active at dusk.

EGGS, LARVAE, PUPAE:

Females lay eggs on Echites species in the dogbane family (Apocynaceae). Echites umbellata, Ficus and Ficus carica are listed as larval hosts.

Jean Haxaire writes, "Several Apocynaceae, contrasting to the classical Moraceae of Pachylia members. Described by Moss (1920) from Para, Brazil on Echites sp. and Zschokkea sp. In Costa Rica, Forsteronia spicata and Mesechites spicata (Apocynaceae)."

Larvae are quite distinct from thos in Pachylia genus.

Larvae pupate in cocoons spun amongst leaf litter.
