A very rare and widespread species in 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.
The adults fly in one generation a year; from mid July till late September. They come to light and sugar.
