Description of Lyonetiidae
The Lyonetiid Moths are very tiny moths with a wingspan of 0.4-1.1 cm. They have lancelike wings that end in narrow points. The base of their antennae is usually surrounded by an eye-cap. As larvae, they often skeletonize leaves, and they pupate in a ribbed, whitish cocoon formed along a twig of the food plant. The cocoon of each species is distinctive, sometimes distinctive enough that the species can be determined.
