Biology. Attracted to light (Yu et al., 2016).

Distribution. China (Hebei, Ningxia, Taiwan); Czech Republic; Denmark; Hungary; Poland; Russia; Turkey; United Kingdom. New record for China.

Note. A very rarely collected species, it may occur in the Netherlands (van Achterberg 1976). The characters are largely as described by Haeselbarth (1973), but length of first tergite 2.0–2.5 × its apical width among Chinese species, which is equal to somewhat longer than reported by Haeselbarth.

This species was reported from part of Turkey which is characterized by markedly eco-geographic continental or montane characters. A single female specimen was collected from an alfalfa ( Medicago sativa L.) field, with Populus sp., Salix sp., and Ulmus sp. around (Çetin Erdogan and Beyarslan 2015), maybe there is some relationships between this species and these plants.

A Chinese specimen from Ningxia (No. 200903100) has slightly more slender antenna (Fig. 8E).
