Eriocraniidae
Eriocraniidae is a family of moths restricted to the Holarctic region, with six extant genera. These small, metallic moths are usually day-flying, emerging fairly early in the northern temperate Spring. They have a proboscis with which they drink water or sap. The larvae are leaf miners on Fagales, principally the trees birch and oak but a few on Salicales and Rosales.
