A rare species in Belgium.
Wingspan 9–11 mm. Has a dominant blackish brown colour of the forewing.
The males are fairly well attracted to the pheromone originally developed for Pennisetia hylaeiformis, Synanthedon vespiformis and Paranthrene tabaniformis.
The larva lives on fungi.
The adults can be observed sitting on the underside of the fungi or on the trunks, and are very hard to flush. The moths mostly hatch before noon, and the males swarm in sunshine during midday close to the fungi.
Due to its diurnal habits it comes not to light and the use of pheromones in suitable habitats is probably the most effective searching method. The species can be attracted by different pheromones of Sesiidae.
The adults fly from May till late September.
