Distribution

European. The species was described from NE Finland, Kuusamo, Jäkälävuoma ( Hackman 1970) and has been since recorded only from Germany ( Chandler 2004). The species has a characteristic eastern distribution in Finland, so far known from the Kainuu and Kuusamo areas ( Hackman 1970, Jakovlev 2011b Jakovlev 2011b) here reported for the first time from NE Lapland.

Ecology

Collected from old-growth boreal forests. Immature stages are unknown. Larvae of Trichonta and Phronia are usually surface feeders on encrusting fungi and slime moulds ( Gagné 1975, Gagné 1981).

Conservation

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