A very rare species in Belgium, mostly known from the southern provinces. Used to be known from some localities in the north, but on 13 September 2006, there was a great influx of this species all over the country. It was observed again in Brabant (formerly only known from literature) and in Antwerpen. (last observation was in 1951!) and the species was new for the provinces of Limburg and West-Vlaanderen.

The larva lives on lichens growing on the bark of different deciduous trees but with a preference for those growing on Quercus. Hibernates as a small larva and pupates in a loose cocoon in a crevice.

The adults fly from mid June till late  September in one generation a year, or possibly with a partial second generation. They come to light and sugar.
