Habitat

Based on the and , likely associated with woodland or forest edge where dogwood (Cornus) occur. As a ground-nesting mining , requires access to bare or sparsely vegetated soil for nest excavation.

Distribution

North America. Documented from Vermont, United States. GBIF records indicate presence in North America broadly, with specific locality data from Vermont.

Diet

Likely oligolectic or specialized on dogwood (Cornus) based on "dogwood andrena," though this has not been explicitly confirmed. As with most Andrena, females provision nest with pollen and nectar for larval development.

Host Associations

Cornus - probable pollen sourceInferred from ; not explicitly documented

Life Cycle

Typical of Andrena: solitary, with females excavating underground nests consisting of branching tunnels with individual . Each is provisioned with pollen and nectar, an is laid, and the cell is sealed. develop through summer, overwinter as or , and emerge the following spring. Males typically emerge before females.

Behavior

Ground-nesting. Females dig nests in soil and forage for pollen and nectar to provision . Males nesting areas seeking females. As a solitary , does not form colonies or produce .

Ecological Role

, likely of dogwood and potentially other spring-blooming plants. Contributes to function through pollen transfer and serves as / for parasitic (Nomada) and other .
