This is a local species, although widely distributed; it was 

 formerly found at Colney Hatch Wood ; it is not uncommon at 

 the side of Bishop's Wood, Hampstead, where it has been ob- 

 served flying about the burrows of Andrena labialis, during the 

 month of May. It appears to frequent hedge-rows and wood 

 sides, in preference to open heaths or sandy situations.
