This appropriately named species is likely the first species to be active in the spring. Males have been found in late March, even with snow still on the ground. Many of these early records are from sap buckets or wounded maples, which provide sugar before the first flowers bloom. Females are specialists on Willows, and this species disappears by mid-May. Primarily a northern species, most records so far are from east of the Greens.

Identification: Medium-large, both sexes are covered in long, silver hairs, including on the abdomen.

Similar Species: Males are similar to Clark’s Mining Bee (Andrena clarkella), another willow specialist.
