Season
April to August.
Food
most often collects pollen from clover and sweet clover (Fabaceae). The Hosts section on its Discover Life species page lists known floral associations based on specimen records and images.
Life Cycle
It nests singly (Chambers, 1949) or in large aggregations (Perkins, 1919). It over-winters as a larva or prepupa (Meidell, 1967). Males are often seen flying in large numbers about the foliage.
Remarks
Introduced long ago from Europe, possibly from transportation of its ground nests in ships' ballast.
It flies into summer, when few native Andrena are flying.
