Dear Sjogro, beste Sjogro (wij kennen elkaar)
This is the larva of Dictenidia bimaculata. Next to Ctenophora these are the only genera with those thick black hairs along the anal lobes. Dictenidia has well developed dorsal and dorso-lateral anal lobes while those in Ctenophora are strongly reduced.
According to Theowald (1967) the species lives in dead hardwood and in the mulm of various deciduous trees: Betula, Fagus, Quercus, Salix.

Thanks atylotus (Ton)! Especially for the additional information. Found this one in a decaying seperated branch of Pinus nigra. Betula and Quercus were also in near vicinity.
