This small, spring bee is only known in Vermont from 6 males collected near Bald Mountain in Rutland County in May 2020.

No photographs could be found for this species. It is thought to be a specialist on Cinquefoils (Potentilla) and Appalachian Barren-Strawberry (Waldsteinia fragarioides).

Identification: Small, males have a yellow clypeus.

Similar Species: Among eastern US bees, Andrena ziziaeformis is probably most similar to the Golden-Alexanders Mining Bee (Andrena ziziae) though the later is active later in the spring and closely associated with Golden-Alexanders. There is another small bee, Panurginus potentillae, that specializes in Cinquefoils but so far it has not been found in Vermont. It is known from MA, CT, and NY.
