Four-banded Flower Bee

Anthophora quadrimaculata

UnknownDDEU

Overview

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

The Four-banded Flower Bee faces severe population declines primarily due to the loss of traditional flower-rich grasslands and coastal dunes where it forages and nests. Agricultural intensification has eliminated many of the wildflower meadows essential for this specialist pollinator, while coastal development has destroyed critical nesting sites in sandy soils. Climate change poses an additional threat by altering the timing of flower blooms, potentially creating mismatches with the bee's emergence periods.

Threat summary

Habitat

The Four-banded Flower Bee inhabits flower-rich coastal grasslands, sand dunes, and traditional hay meadows across parts of Europe. It requires sandy soils for excavating nesting burrows and depends on diverse wildflower communities, particularly favoring plants in the pea family for pollen collection.
