Apparently a local species, but widely distributed. 

 Smith says it is not rare about Hampstead and Highgate 

 and also records it from Scotland. I have never taken it 

 myself. Other localities recorded are Glanvilles Wootton ; 

 Lulworth; Isle of Wight; {Bale). Exeter; [Parfitl). 

 Edgbaston ; (MarshalT). Smith says it is parasitic on 

 A)idrena lahialis and "A rufa" (1 fulva). Schmiedeknecht 

 gives it as parasitic on Andrcwt pratensis.
