On 11 May 1939, E Ernest collected a female of this bee at Princes Risborough, Buckinghamshire (Yarrow & Guichard, 1941). This remains the only record for the bee in Britain. The specimen is in the collection of the Natural History Museum, London.
This bee occurs throughout much of central and southern Europe (Dylewska, 1987) but is uncommon. There are apparently no records from Fennoscandia, Spain, Italy and the Mediterranean islands (Gusenleitner & Schwarz, 2002).
