Eriocraniidae
Sparkling Archaic Sun Moths
Eriocraniidae is a family of primitive moths restricted to the Holarctic region, comprising six extant genera. Adults are small (forewing length 4–7 mm), diurnal, and typically active in early spring, often flying in sunshine around host trees. Larvae are leaf miners on woody angiosperms, primarily in the order Fagales, with most species feeding on birch (Betula) and oak (Quercus). The family retains many ancestral morphological features and represents one of the earliest diverging lineages within Lepidoptera.
