"Until recently, both P. ilus and P. passerina were treated as two of the many forms of the variable P. lusca. However, both are now recognized as species. P. ilus can be easily distinguished from the other two by the pale yellow anal patch on the hindwing underside (greyish-buff in P. l. lusca and P. passerina)."

FLIGHT TIMES:

Perigonia ilus has been taken in Costa Rica in all months of the year. March and October flights have been recorded in French Guiana.

ECLOSION:

Moths emerge from pupae in shallow underground chambers.

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.

Here is a "pair that came to the house light in copulation. Note that she is old and worn, and he is very new and fresh.

It was very hard to separate them without tearing abdomens, even when newly killed and relaxed.

When they were flying, both had their wings going frantically."

EGGS, LARVAE, PUPAE:

Larvae have a yellow tail horn, a green body and a dark blue stripe down the back. There are several color morphs. Larvae feed on Calycophyllum candidissimum and Guettarda macrosperma of the Rubiaceae family.

Ezequiel Bustos writes, "This is one of the most common species in Misiones province, Argentina, especially because the larvae feed in the Ilex paraguariensis plantations (yerba mate), the national drink of Argentina."

Ilex paraguariensis is a species of holly (family Aquifoliaceae) native to subtropical South America. People steep the dry leaves (and twigs) in hot water, rather than boiling water. The beverage is a slightly less potent stimulant than coffee and it is much gentler on the stomach.

Moths emerge in as few as twelve days after pupation.

Larvae are subject to parasitization by Thyreodon maculipennis subfamily Ophioninae, family Ichneumonidae.
