Richards (1980) considered this species to be local but widespread throughout the British Isles northwards to Inverness, although much more common in the south. Currently available data suggests it is still generally spread across England, with no data for the rest of the British Isles. Lomholdt (1984) states that this is a wasp of only sporadic occurrence in Denmark and Fennoscandia, although widely spread across Europe, and with records from Kazakhstan, Mongolia, China and Japan. It is also found in north-eastern USA and adjacent parts of Canada.
