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.
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.
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.
Antwerpen, Schoten, 13 September 2006.
