A common species throughout Belgium.
A local form occurs on the seacoasts of northwestern Europe, sometimes treated as a species "Mythimna favicolor". The species status is very controversial. (including no difference in DNA at all)
We believe that this is a form of Mythimna pallens.
Hibernates as a small larva low down in the vegetation. The adults come to light and sugar.
The adults fly in two generations a year from mid May till mid October. Individuals of the second generation are most numerous.
