Widespread across England and Wales, Brassy Mining Bees inhabit various environments, including gardens, meadows, woodland edges, and urban parks. They are particularly fond of sunny spots with bare or sparsely vegetated soil, which they use for nesting.

Notable food sources include dandelions, brambles, buttercups, knapweeds, and scabious. Their foraging activity plays a vital role in pollinating various wildflowers.
