Notes. A single male was collected in an alluvial forest, dominated by Populus nigra (L.), while sunbathing on a standing dead tree of Populus spp. Only a few scattered records from central and south-eastern Europe are known, while this species is more frequent in Scandinavia (van Steenis et al. 2020).
