About Eana osseana (Scopoli, 1763)
Eana osseana (Scopoli, 1763) has a wingspan of 16–23 millimetres (0.63–0.91 in). Its basic coloration is pale brown, with a small number of unclear brown markings. Meyrick's description of the species notes that forewings are very elongated, the costa is almost straight, and the termen is slightly sinuate. Forewings are brownish-ochreous, sometimes with a ferruginous tinge, and rarely whitish-ochreous. An irregular spot in the disc before the middle, a second irregular spot beyond the middle, and a triangular apical patch are fuscous; these markings are often indistinct, and sometimes entirely absent. Hindwings are grey. Adult moths fly from June to August, and are attracted to light. The larvae live inside a silken tube. They are polyphagous, feeding on a wide range of herbaceous plants, grasses, and mosses. This species is widespread across most of Europe, the East Palearctic realm, and the Nearctic realm. Its preferred habitats are grassland, downland, and moorland.
