Anthophore estivale

Anthophora aestivalis, commonly known as Anthophore estivale, is a robust solitary bee species belonging to the family Apidae. This medium-sized bee displays the characteristic features of the Anthophora genus, with a densely hairy body ranging from dark brown to black coloration, and females possessing specialized pollen-collecting structures called scopae on their hind legs. Males are typically smaller and more slender than females, with longer antennae and distinctive pale facial markings.

The species exhibits ground-nesting behavior, with females excavating burrows in sandy or clay soils where they provision individual cells with pollen and nectar for their developing larvae. Active during late spring and early summer months, these bees demonstrate strong fidelity to specific flowering plants, making them important pollinators for native wildflower communities. Anthophora aestivalis is currently classified as Critically Endangered (CR) by the IUCN, reflecting severe population declines and restricted distribution.

The species appears to have historically occurred across limited regions of Europe, though precise range boundaries remain poorly documented. Despite its precarious conservation status, recent targeted surveys have successfully relocated small populations in protected areas, and specialized habitat management programs are showing promise for supporting remaining colonies. Conservation efforts focusing on maintaining suitable nesting sites and preserving native flowering plant communities offer hope for this rare pollinator's recovery.

This species inhabits open grasslands, meadows, and scrubland areas with sandy or well-drained clay soils suitable for excavating nesting burrows. The habitat must support diverse native flowering plants that bloom during the bee's active period in late spring and early summer.
