A rather small, metallic green bee, with white tomentose hair bands on the gaster. Great care must be taken, particularly with females, when separating this species from the common H. tumulorum. Best identified from the male, which should always be dissected to show the vital character in the genitalia.
A southern restricted species, recorded only from Dorset to Kent and north to West Norfolk. An Holarctic species, ranging from Spain and England to the far East of Russia but apparently not common; also found in North America. A variable species across its range with several listed infra-specific names.
