The forewing has a dark, slightly irregular, inwardly concave, thick line running from the apex to the anal angle. A prominent, very straight, dark am line is outwardly shaded in dark brown more widely along the inner angle, tapering toward the costa. There is a small black dot at the base of the costa midpoint, and a slightly larger black, short black streak in the cell.

The hindwing yellow band varies from broad and well developed (form lusca) through divided (form interrupta) and highly reduced (form restituta), to absent (form tenebrosa). The tornal patch on the hindwing underside is buff.

The genus name "Perigonia" POSSIBLY was chosen to reflect the bud like tufts of hairs near the tip of the abdomen.

"Lusca" means "one-eyed" or "half-blind".

The pronunciation of scientific names is troublesome for many. The "suggestion" at the top of the page is merely a suggestion. It is based on commonly accepted English pronunciation of Greek names and/or some fairly well accepted "rules" for latinized scientific names.

The suggested pronunciations, on this page and on other pages, are primarily put forward to assist those who hear with internal ears as they read.

There are many collectors from different countries whose intonations and accents would be different.

SCENTING AND MATING:

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

EGGS, LARVAE, PUPAE:

Larvae have a yellow tail horn, a green body and a dark blue stripe down the back. There is at least one color morph. Larvae feed on Guettarda macrosperma of the Rubiaceae family.

Coffee (Coffea species) in the madder family (Rubiaceae) also serve as hosts and larvae can become serious pests. In Florida, caterpillars have been reared on tawnberry holly (Ilex krugiana) in the holly family (Aquifoliaceae) and on Rough Velvetseed (Guettarda scabra).

Genipa americana, Gonzalagunia, Ilex paraguariensis, Rondeletia, Coffea arabica, Gonzalagunia spicata and Ilex krugiana are also reported as hosts.

On the Galapagos Islands Cinchona succirubra is reported as a larval host.

Moths emerge in as few as twelve days after pupation.

Larvae are subject to parasitization by Leschenaultia sp. 14 of the Tachinidae family. Ben Trott sends the following images from Quintana Roo, Mexico:
