The vast majority of bees are solitary, living out their lives as single bees, provisioning single nest cells.
I saw these drop into my garden, Mating Southern hawkers.
A large, inquisitive Hawker usually seen individually. It may fly quite close to investigate observers. The spots on segments S8-10 are joined, unlike other Hawkers. The ante-humeral stripes are broad and strongly coloured The costa is dark and there is an elongated triangular mark on S2. The male is brightly marked on a dark background, usually apple green except for S8-10, which are pale blue. Occasionally, all pale blue marked individuals are seen.
The female is brown with bright green markings.
Breeds in water line vegetation in well-vegetated, small ponds, often in garden ponds. Hunts well away from water and may be found hawking woodland rides well into the evening.
Status & Distribution
Very common in southern and central England and Wales, more local elsewhere (vagrant only to Ireland).
They were there for about 30 minutes
