Remarks. This species widely distributed in Palaearctic and Nearctic regions. In Beringia, it is known from Northeast Yakutia, Magadan region, Alaska, Yukon, and the Northwest Territories. There is a single generation per year in most of Eurasia and North America. Winter is passed in the adult stage; nymphal growth is accelerated, probably because of long day-length (Vickery, 1984).
