A very rare and local species in Belgium, with most observations in the northeast part of the country.
The adults fly in two generations a year: during May and June and a small second generation in August. They are active during hot weather around midday and afternoon. They come to light.
The larva feeds in the young stems of Pinus sylvestris and Picea excelsa. They also have been found in old galls of tortrix Retinia resinella and of pyralid Dioryctria abietella.
