Andrena angustior (Kirby, 1802)

Description and notes

The females of this medium-sized Andrena are very like those of Andrena bicolor Fabricius, but can be found in May, between the main flight periods of that species. Careful examination of the clypeus of female Andrean angustior will show a faintly impressed vertical line, not present in bicolor. Males of Andrena angustior seem to be generally scarce, the reason is not known.
