It is a widespread Palaearctic species, known from several European countries ( Chandler 2013), and new for the Romanian fauna. Larvae are polymycophagous, feeding on several agaric mushrooms ( Jakovlev 1994, 2011). According to Ševčík (2010), B. tenella is an uncommon species in the Czech Republic, perhaps preferring Pholiota species as host fungi.
