This species’ range extends through central and northern Europe to southeast Russia.

[1] The larvae feed on apple (Malus), plum, cherry (Prunus), birch (Betula), lime (Tilia), beech (Fagus).

In O. fagata, the uncus is more pointed with a broader and flatter base that is more triangular in O. brumata (Kellner, 2005).

[5] From mid-May until early June, mature larvae fall from trees to the woodland floor to pupate in the soil.

Females lay eggs on twigs close to leaf buds in November, where they overwinter.

[7] The larva of this moth can be a serious pest of fruit trees in northern Britain by attacking the foliage and blossom.
