 Adelidae are usually closely restricted to particular host plants, in which the females insert their eggs or just lay among leaf litter, and the caterpillars make a case, completing their development on the ground.Fairy longhorn moths feed in sunshine on nectar from the flowers of herbaceous (woody) plants.Fairy longhorn moths belong to the superfamily Adeloidea, one of the basal ("monotrysian") branches of the advanced moth infraorder Heteroneura.
