02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

Northern Colletes faces severe population declines due to habitat loss from agricultural intensification and urban development destroying the specialized nesting sites and floral resources this solitary bee requires. Climate change is altering flowering phenology of key plant species, creating temporal mismatches between bee emergence and nectar availability, while pesticide use in agricultural landscapes poses additional mortality risks.

Key Facts

03Habitat

Habitat & Distribution

Northern Colletes inhabits sandy coastal areas, heathlands, and open grasslands where it constructs underground nests in well-drained sandy soils. The species requires proximity to specific flowering plants including asters and other late-season composites that provide essential pollen and nectar resources.
