of the Lepidoptera of Belgium

Pyrausta despicata (Scopoli, 1763)

A local species in Belgium, mainly observed in the southern part.

The larvae live gregariously in silken galleries close to the base of a leaf, feeding nocturnally on the underside of the leaves of Plantago lanceolatum or Plantago major. They pupate in a tough whitish cocoon in the soil.

The adults fly in two difficult to separate generations a year; onwards from mid April towards June and in July-August. They are active in the sunshine and at dusk and later come to light.
