Andrena lagopus is a species of mining bees belonging to the family of Andrenidae.

[1] This species is present in the palearctic realm (Austria, France, Germany, Hungary, Italy, Poland, Slovenia, Spain, Switzerland, Yugoslavia, North Africa and in Northern Asia, excluding China).

[2][3] This thermophile species prefers areas below 500 m. It can be found from the end of April to the end of June in rape fields, arable fields, meadows, and gardens.

These bees mainly feed on nectar of Brassicaceae (Brassica napus, Barbarea vulgaris and Cardamine pratensis) and Caryophyllaceae (Silene gallica).

Females of these membrane-winged bees have the forewings with only two submarginal cells, unlike those of all other Andrena species.
