Lithacodia uncula

Lithacodia uncula, the silver hook, is a small noctuid moth first described by Carl Alexander Clerck in 1759. It has a very wide Palearctic distribution, from the western French Pyrenees across Europe to Japan. In the north it reaches south and central England, Ireland, the Baltic area of Scandinavia, Finland and northern Russia, while it is largely missing around the Mediterranean apart from a few small occurrences. The range continues east through the Russian Far East, northern China, Korea and Japan. The wingspan is 20 to 22 millimetres, with short broad wings. The forewing is olive brown, darker on the disc, with a broad tannish-peach streak along the costa and another on the inner margin, and the hindwing is paler. Adults fly from May to September depending on the location. The larva is green with a darker dorsal line and feeds on various grasses and Carex species.
