Cockerell, 1930

Short-palped Miner, short-tongued miner bee

Andrena brevipalpis is a solitary mining in the , described by Cockerell in 1930. It is to North America, with confirmed records from Vermont and broader North distribution. The species is an oligolectic , pollen exclusively from Rhus (sumac) flowers. Like other Andrena species, it nests in the ground and is active during spring.

Habitat

Ground-nesting requiring bare or sparsely vegetated soil for nest excavation. Associated with supporting its Rhus (sumac).

Distribution

North America; confirmed present in Vermont, United States. Broader range across North America based on distribution records.

Seasonality

Spring-active, consistent with other Andrena and its association with spring-blooming Rhus flowers.

Diet

Oligolectic pollen on Rhus (sumac) flowers. likely consume nectar from these and potentially other flowers.

Host Associations

Rhus - pollen sourceoligolectic pollen

Life Cycle

Solitary with ground-nesting biology: females excavate tunnels, provision with pollen and nectar, lay , and develop underground. Males typically emerge before females.

Behavior

Females dig individual nest burrows in soil. Males nesting areas seeking mates. As an oligolectic , females exhibit flower constancy to Rhus during pollen collection.

Ecological Role

of Rhus (sumac) flowers. Contributes to spring services in forest and woodland edge where sumac occurs.
