Remarks.

This is a widespread species that is distributed from western Europe through the Caucasus and Siberia to the Far East (Sama 2002, Danilevsky 2018a). The species is ecologically associated with Populus tremula but it can also develop in the wood of other tree species such as Salix, Betula, Quercus, Malus, Sorbus, Robinia pseudoacacia, Fraxinus and Rosa (Starzyk and Partyka 1993). According to Sama (2002), adults are active from April to August and can be found on their host plants or on the flowers of various plant species.

Only a single female was attracted to the artificial light source (Fig. 15H) at the edge of a mountain deciduous grove that consisted mainly of Populus, Betula and Salix (Fig. 15C).
