Dotted Shade

Eana osseana has a wingspan reaching 16–23 millimetres (0.63–0.91 in). The basic coloration is pale brown, with a few obscure brown markings. Meyrick describes it - Forewings very elongate, costa almost straight, termen slightly sinuate brownish-ochreous, sometimes ferruginous-tinged, seldom whitish- ochreous; an irregular spot in disc before and another beyond middle, and a triangular apical patch fuscous, often indistinct or sometimes obsolete. Hindwings grey. Adults fly from June to August and they are attracted to light. The larvae live within a silken tube. They are polyphagous, feeding on many herbaceous plants, grasses and mosses.

This species is widespread in most of Europe, in the East Palearctic realm and in the Nearctic realm. It prefers grassland, downland and moorland.
