Richards (1980) noted a widespread distribution from southern England to southern Scotland, plus south Wales and Ireland. This distribution probably remains true, but with very few Scottish and Irish records.
This species has a disjunct distribution globally, being present across central and northern Europe (as far east as Kazakhstan) and then Japan (Bitsch & Leclercq, 1993).
