Nepticuloidea is a superfamily of usually very small monotrysian moths that are characterised by small or large eyecaps over the compound eyes. It comprises two families, the "pigmy moths" (Nepticulidae), with 12 genera which are very diverse worldwide and are usually leaf miners, and the "white eyecap moths" (Opostegidae), also worldwide but with five genera and about a ninth as many species, whose biology is less well known.
Nepticulidae is a family of very small moths with a worldwide distribution. They are characterised by eyecaps over the eyes. These pigmy moths or midget moths, as they are commonly known, include the smallest of all living moths, with a wingspan that can be as little as 3 mm in the case of the European pigmy sorrel moth, but more usually 3.5–10 mm. The wings of adult moths are narrow and lanceolate, sometimes with metallic markings, and with the venation very simplified compared to most other moths.
Opostegidae or "white eyecap moths" is a family of insects in the order Lepidoptera that is characterised by particularly large eyecaps over the compound eyes. Opostegidae are most diverse in the New World tropics.
