The adult bees will overwinter. The females hibernate in or near the nest. As soon as the temperature rises in spring, they emerge from their wintering site. The Grey-patched Mining flies from mid-March to mid-July. The males will actively fly around hedges, shrubs, or near the nesting areas to search for females to mate with.

After mating, the female digs her nest in roadside verges, slopes, sandy paths, or among vegetation on dry or damp lawns. This bee species typically nests in patchy or sloping meadows with short grass, such as lawns or pastures. The nest consists of a main tunnel with side tunnels leading to the brood cells. In each brood cell, the female lays an egg, topped with a supply of pollen and nectar for the future larva.

The larva hatches from the egg and feeds on the food stores. The larva grows and molts several times, after which it pupates into a bee. The pupal stage takes place underground in the brood cell.

The adult bees emerge from the chrysalis in the spring. The emerging females begin foraging, mating, and building new nests. They then hibernate, and the cycle repeats.
