Overview

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

The Shrill carder bee faces severe population declines primarily due to the loss of flower-rich grasslands and traditional hay meadows across its range. Agricultural intensification has eliminated crucial foraging plants like red clover, field scabious, and knapweed that this species depends on for nectar. The bee's late-flying season (active until October) makes it particularly vulnerable to habitat fragmentation, as it requires continuous flower resources when most other plants have finished blooming.

Threat summary

Habitat

The Shrill carder bee inhabits flower-rich grasslands, traditional hay meadows, coastal dunes, and rough pastures with abundant late-flowering plants. It shows particular preference for areas with red clover, field scabious, and other composite flowers that bloom into autumn.
