Distribution

Palaearctic. The species is known from Central and eastern Europe ( Chandler 2004), Sibera and Russian Far East ( Zaitzev 2003). In Fennoscandia only recorded from Sweden (hemiboreal zone, Kjaerandsen et al. 2007) and Finland. The majority of the Finnish records, five out of six, are from the south boreal zone. One of the records is from NW Lapland, north boreal zone.

Ecology

Finnish records are invariably from Vaccinium myrtillus type old-growth boreal forests. Immature stages are unknown, but are likely associated with polyporous fungi (see Dynatosoma cochleare ).

Conservation

Red-listed in Finland (NT, Penttinen et al. 2010).
