A rare species throughout Belgium.
The three Amphipoea species that occur in Belgium are very similar and in most cases can hardly be distinguished with certainty on the basis of their external characteristics. They have an almost identical wing shape and drawing and the same degree of variation. Therefore genitalia research is necessary to determine the right species.
Hibernates as an egg and pupates underground. The adults come to light and sugar.
The adults fly from early July till late September in one generation.
