Feathered Gothic Tholera decimalis

(Poda, 1761)

---

Wingspan 32-45 mm.

Occupying rough grassland and downland, this moth is widely distributed, though local, over much of Britain, and is common in parts.

The adults are on the wing in August and September, when the males in particular are attracted to light.

A grass-feeding species, the young larvae eat the blades, and when more mature, descend to ground level and devour the stems.
