This species is probably extinct in Britain, with all records from more than 100 years ago.
The records came from North Hampshire and East Suffolk (Richards, 1980). The Suffolk observations possibly relate to the areas around Ipswich and Lowestoft (Falk, 1991).
Overseas, this is extremely rare in Fennoscandia, but widely distributed in the Palaearctic to Japan (Lomholdt, 1984).
