Distribution

European. A rare and poorly known species, so far only known from the Netherlands ( Barendrecht 1938), Great Britain ( Chandler 1992), Norway ( Anonymous 2010) and Germany ( Plassmann 1988). The first record from the Baltic sea catchment area, new for Finland.

Ecology

Finnish sampling locality is a swampy lake shore with luxuriant vegetation. Collecting sites reported by Chandler ( Chandler 1992) are wetlands and the only known Norwegian locality is a lake shore wetland ( Anonymous 2010). Relatively long flying period, specimens were caught between May and October. However, 60% of the caught specimens were trapped between 23rd of August - 20th of October. Larval habitats are unknown. Generally, Leia larvae spin a slimy web on the under surface of fungi and dead wood ( Jakovlev 2011a). In addition, some species have been reared from the nests of birds and mammals ( Falk and Chandler 2005) and from tussocks of grasses and sedges ( Ševčík and Roháček 2008).

Conservation

Red-listed in Norway (VU, Anonymous 2010, Gammelmo et al. 2010).
