Local name: trubbkägelbi

UnknownDDEU

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Coelioxys obtusispina faces significant threats from habitat fragmentation and loss of its specialized host bee populations. As a cleptoparasitic species that depends entirely on specific solitary bee hosts for reproduction, any decline in host abundance directly impacts its survival. Agricultural intensification and urbanization have reduced the availability of suitable nesting sites and floral resources needed by both the species and its hosts.

Threat summary

Habitat

This cleptoparasitic bee inhabits open woodlands, forest edges, and semi-natural grasslands where its solitary bee hosts construct their nests. It requires areas with diverse flowering plants and suitable substrate for host bee nesting, including sandy soils and exposed earth banks.
