Synonyms and other taxonomic changes
Author: OPOSTEGIDAE Meyrick, 1893
Explanation of Names
derived from the Greek opos (eye) plus stege (roof)
only 11 species in America north of Mexico, 3 in the west (1)
Adults - larger than nepticulids, with enormous eye caps, completely obscuring the eyes from a frontal view. Wings relatively broad with apices often bent upward, white with sparse dark markings (1)

Larvae - extremely slender, legless, flattened, with callosites on second and third sthoratic venter, adapted for sub cutaneous mining (1). The head structure of Opostegidae, roughly triangular in shape, resembles no other moth larva (2)
primarily cambium miners in woody stems and fruit (1)
adult Opostegidae have been observed to burrow their way into small crevices for concealment. Certain aspects of their morphology, particularly the enlarged antennal scape (or eyecap) that can completely cover and thus protect the eye and the generally depressed body are apparent adaptations for this behavior (2)
