Andrena humilis – Gog Mogogs

New species to me.

Description and notes
A distinctive, medium-sized Andrena, the female having a coat of golden hairs on the last two tergites. It shares this feature with the slightly smaller A. fulvago (Christ), but has dark hind tibiae, rather than pale ones. The male is one of the small group which have bright yellow markings on the clypeus. This species may be quite plentiful where it occurs, usually, but not exclusively, on sandy soils, but is decidedly local.

Listed as Notable B in Falk (1991) (now known as Near Threatened Nb).
Habitat
Most often associated with sandy soils, although also known from coastal head deposits where the soils are friable.
Flight period
Univoltine; May to July.
Nesting biology
May nest colonially or singly in areas of bare, firm, usually sandy, soil exposed to the sun.
Flowers visited
It seems to restrict all flower visits to yellow-flowered Asteraceae.

Parasites
The cleptoparasitic bee Nomada integra Brullé is specifically associated with this species. It has been found stylopised elsewhere in Europe.
