A very rare and local species in Belgium, nowadays mainly restricted to the Kempen.
A species that is very often confused with the more common Plusia festucae.
Hibernates as a small larva and pupates in a cocoon, spun among the food plant. The adults come to light.
The adults fly in two generations a year; from late May till late September. The second generation is partial.
