Grey-Backed Mining Bee
Andrena vaga
Andrena vaga, the grey-backed mining bee, is a species of solitary bee which is found in most of Europe but which is very rare in Great Britain, where it may be recolonizing in the south-east after previously being extirpated. It specialises in feeding on the pollen of willows. Source
