Distribution

Palaearctic. Widely distributed in Europe ( Chandler 2004, Ševčík and Kurina 2011) and also recorded from the Russian Far East, Kuril Islands ( Zaitzev 2003). In Fennoscandia reported from Finland ( Hackman 1980), Norway ( Gammelmo and Søli 2006) and Sweden ( Kjaerandsen et al. 2007). New to the Republic of Karelia.

Ecology

The Karelian specimen was collected in herb-rich spruce dominated forest. The larvae of Dynatosoma usually live within fruiting bodies of soft polypores ( Ševčík 2010, Jakovlev 2012). Their presence may often be detected by white frass that the larvae extrude from their burrows onto the surface of the fungus ( Edwards 1925).
