Alekseev), 23.VIII-21.IX.2009 ( 1 ex. , Fageto-Piceetum forest, window trap on an old beech, leg. V . Alekseev). Comments: This dendrophilous species is widespread in the whole Baltic region and has been reported from Belarus ( Alexandrovitch et al. 1996 ) and all the Baltic and Fennoscandian States except Finland , Karelia and Norway ( Silfverberg 2004 ). On the territory of the former East Prussia, the findings were not numerous: the species has been recorded from northern Poland and Königsberg [Kaliningrad]. It appears not to be rare in the region, but can be found by purposeful searching in appropriate habitats (rotten wood of the basal part of old deciduous trees, often inhabited by ants of Lasius spp. ).
