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.
Native
Hibernates as a small larva low down in the vegetation.
The adults come to light and sugar.
