DISTRIBUTION:

Automeris moresca (wingspan: males: 70-86mm; females: 102-114mm) flies in tropical rain forest from sea level to 1250m in the Guyano-Amazonian region:
French Guiana: Camopi, Cayenne, Regina, Belizon, Cacao, Coralie, St. Elie, Kourou, Sinnamary, Acarouany, Saint-Laurent-du-Maroni, Saint-Jean-du-Maroni, (Camp Caiman, road to Kaw, WO);
Venezuela: Amazonas, Bolivar;
Ecuador: Napo and Sucumbios (LTR); Zamora-Chinchipe (PO)
Peru ??;
Brazil: Para, Amazonas, (probably Amapa and Roraima, WO??).

It probably also flies in Guyana and Surinam.

French Guiana is the specimen type locality.

Lemaire groups moresca, themis, tristis and phrynon as having abdomens that are usually orange-ringed (light or dark), matching the basal area of the hindwings. The forewing postmedial line is only slightly preapical. The hw eyespot is usually ringed with yellow.

Themis, a small species, has a relatively broad yellow ring around the hindwing eyespot; tristis has a very dark basal median area (male) on the hindwing with the female being uniformly dark; phrynon has a distinct wing shape and pattern.

Automeris moresca has a squarish, greyish-orange-brown forewing, only scarcely produced at the apex. The pm line, inwardly lined with a thin yellowish-orange scaling, meets the inner margin quite close to the anal angle. The am line is zigzagged and runs obliquely from the costa to the midpoint of the inner margin. The fw cell spot is grey and is oriented perpendicular to the costa.

The pupil of the hindwing eyespot is small and is usually well covered with white scaling. The iris is dark brown, and sometimes the eyespot is thinly lined with yellow.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Moths have been taken in January-February, April, June-August and November-December, suggesting three-four broods at least.

Larvae feed on Robinia pseudoacacia, Salix and Prunus laurocerasus. Larvae have also been reared on Pyracantha and Gleditsia triacanthos

ECLOSION, SCENTING AND MATING:

Males use their more highly developed antennae to seek out females who release an airbourne pheromone into the night sky.

EGGS, LARVAE, COCOONS, AND PUPAE:

Eggs are deposited in clusters of 6-40+ on hostplant twigs. Larvae have urticating spines and are gregarious, especially in the early instars.

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.

I am not aware of the source for Automeris, but moresca is the name of a dance, and may have been chosen to refer to the elaborate costumes the dancers would wear.
