  • Eupithecia subfuscata ussuriensis Dietze 1910 (Russian Far East, Japan)

Description

The forewings of this species are grey (occasionally with an ochreous tinge) marked with pale fascia and radial lines which give it a mottled appearance. There is a pale sub-marginal line and a small discal spot. The hindwings are much paler and plainer also with a small black discal spot.[2] Melanism is quite common in this species. The wingspan is 17–21 mm.

Biology

The adults fly in May and June with a second brood sometimes emerging in August. The species flies at night and is attracted to light.

The species overwinters as a pupa.

Larval food plants

The larva feeds on the leaves and flowers of a wide range of plants.
