A very rare and recent (2018) species in Belgium.
Native
The eggs are laid on nearby trees or other suitable surfaces. The larva overwinters in its first instar, then in early spring it leaves its hibernaculum and moves to a suitable food plant, sometimes assisted by the wind.
Adults come to the species-specific pheromone.
The adults fly from late June towards late July.
The species is highly polyphagous on cereals, grasses, legumes and flax.
