Andrena thoracica – St Davids

Excited folks, I made a wrong Id the other day this is not a fresh Andrena carantonica. It is a faded but very late Andrena thoracica I did not consider this bee because its known flying time ends in August.

This species is locally common in coastal localities in southern Britain, but is also known from a number of inland sites, often on heathy soils, where it rarely attains the abundance of some of its coastal locations. Males patrol nesting areas, flying extremely quickly along the edge of cliffs, just below the top edge. It is widespread, but rarely common, in Europe. It is also found throughout the steppe regions of Asia.

Status (in Britain only)
This species is not regarded as being scarce or threatened.

May be found in open, sandy-grassland habitats, particularly where these are associated with exposed vertical cliffs, which provide the favoured nesting sites.

Flight period
Bivoltine: March to May and July to August

Pollen collected
Widely polylectic.

Nesting biology
Strongly associated with vertical cliffs of sandy material, but may also use more level sandy areas.
