Essex Red Data List comment
forages on yellow composites. Now widely distributed.
The bee is restricted in Britain to several south-eastern counties. Apart from one very old unconfirmed Essex record of this species mentioned in Else (1998), the species was first recorded in the county near South Ockendon in 1999, and has subsequently been found at a number of sites near the Thames in South Essex. In 2007 it was recorded from brownfield land in Colchester, and is clearly spreading northwards. The bee nests in holes in dead wood, and has been observed nesting in dead, broken Rubus stems and flying about masonry (Else, 1998). Resin, probably from various sources, is used in nest construction and the females gather pollen from composites (Asteraceae), especially Ragwort Senecio jacobaea. References
