A superfamily of insects in the Lepidoptera order restricted to the Holarctic region, with six genera (see Davis, 1978; Mizukawa et al., 2004). 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[1] on Fagales, principally the trees birch Betula and oak Quercus but a few on Salicales and Rosales (Kristensen, 1999).
Note: there also exists a brachiopod genus Neocrania Lee & Brunton, 1986 but this has been renamed Novocrania Lee & Brunton, 2001 [2]
