5. Opostegidae – white eye-cap moths

Minute (6–12 mm wingspan) moths with predominantly white wings. Th ey can be separated from most other small moths by the combination of a tuft of hairlike scales on the head, presence of an antennal eye cap, and primitive wing venation. They can be separated from the Nepticulidae by the absence of extensive dark areas on the forewings. Larvae are leafminers.

Over 100 species of Opostegidae are known worldwide, with many undescribed species expected to be found. Ten species are known from North America; one of these is known from AB. Taxonomic coverage of the Opostegidae is excellent: Davis (1989) provided a genus-level treatment and catalog for the world fauna, Diskus and Puplesis (2003) a catalog of the world fauna, and Davis and Stonis (2007) a monograph of the New World fauna.
