Species text
Andrena trimmerana is a much declined mining bee recorded from disturbed coastal areas such as soft rock cliffs, and inland from heathland, woodland edge and moorland. Nesting probably occurs in warm, sparsely-vegetated areas. This species is double-brooded and seasonally dimorphic, which has caused much taxonomic confusion. Pollen sources in Britain are not established but the spring brood is often seen on Salix and Prunus, while the second brood has been seen visiting Rubus and umbellifers. References
