Introduction
There are 47 known members of the genus Theope, distributed variously from Mexico to Argentina and Bolivia.
The species vary considerably in appearance - e.g. the upperside of eudocia is bright orange with a broad black apex within which is a patch of metallic violet-blue. At the opposite extreme, nycteis is pale brown, mottled heavily with blackish, and has a prominent double-pupilled ocellus at the apex of the hindwing. The vast majority of species including eurygonina are black on the upperside, with a dazzling metallic blue sheen across the basal half of the forewings and over the entire surface of the hindwings.
The undersides of Theope are typically either plain white with a series of tiny submarginal spots, or are cryptically marked in shades of brown. The latter group resemble small dead leaves, and have falcate forewings. The double-banded underside of eurygonina is unique in the genus. Colombian specimens are more strongly marked, and have small but prominent submarginal ocelli.
Theope eurygonina is currently known only from Colombia, Brazil and Peru, but probably occurs over much of South America.
Habitats
This species is found in rainforest at altitudes between about 200-800m.
