Hebrew Character

The typical form of this common species has a distinct black mark on the forewing that is unique among spring-flying moths, but in northern parts, this mark may be the same as the ground colour, or paler.

This moth spends the winter as a pupa in an underground cocoon, with the adult fully formed inside. The caterpillars can be found between April and July, feeding mainly at night on the buds and then the leaves of their foodplant.

Adults fly late in the night, even in cold conditions and can be seen feeding at sallow blossom, also regularly attracted to light and sugar.

Flight Season

Flies throughout March and April in one generation. In mild weather, small numbers may emerge in late autumn or winter.
