Guernsey Nomad Bee

Nomada similis

UnknownLCEU

Overview

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

The Guernsey Nomad Bee faces severe habitat loss due to agricultural intensification and urban development across its limited range in the Channel Islands and coastal Europe. As a cuckoo bee that parasitizes specific mining bee hosts, it is particularly vulnerable to the decline of its host species caused by pesticide use and loss of flower-rich grasslands. Climate change poses an additional threat by altering the timing of emergence between this species and its hosts, potentially disrupting critical reproductive cycles.

Threat summary

Habitat

This nomad bee inhabits coastal grasslands, cliff-top meadows, and sandy areas with abundant wildflowers, particularly in the Channel Islands and select coastal regions of western Europe. It requires proximity to the nesting sites of its host mining bees, typically in well-drained soils with sparse vegetation cover.
