Distribution

Palaearctic. Widely distributed in Central Europe, Mediterranean countries (Spain, Italy, Malta) and found also in Israel, the Near East ( Chandler 1994, Chandler 2004) and Northern Caucasus ( Zaitzev 1994). From northern Europe only known from Sweden ( Kjaerandsen et al. 2007) and Denmark ( Petersen and Meier 2001). Included in the recent Red List assessment of Finnish species ( Penttinen et al. 2010), but here formally reported for the first time from Finland.

Ecology

Larvae are saproxylic. They develop on the surface of dead wood impregnated with fungal mycelium ( Zaitzev 1994). Finnish specimens were collected in semi-urban habitats (Helsinki city parks) and in herb-rich forests with exceptionally fertile soils (Linnansaari, Rantasalmi) in the southern parts of the country.

Conservation

Threatened species in Finland (VU, Penttinen et al. 2010)
