Flat-ridged Nomad Bee
Nomada obtusifrons
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Flat-ridged Nomad Bee faces severe population declines primarily due to the loss of its specialized nesting habitat and the decline of its host bee species. As a cleptoparasitic species that depends entirely on specific solitary bee hosts for reproduction, any reduction in host populations directly threatens its survival. Agricultural intensification and urban development have fragmented the sandy soils and sparse vegetation areas where both this species and its hosts establish nesting sites.
Habitat
This species inhabits areas with sandy soils and sparse vegetation where its solitary bee hosts construct ground nests, typically found in coastal dunes, heathlands, and sandy grasslands. It requires proximity to flowering plants that provide nectar sources for adults, particularly favoring areas with diverse wildflower communities adjacent to suitable nesting substrates.
