Solitary Bee Conservation: The Hidden Majority of Our Pollinators

Solitary bees — which include mason bees, mining bees, and leafcutter bees — make up over 90% of bee species but receive a fraction of the conservation attention devoted to honeybees.

Key Facts

Over 250 species of wild bee live in the UK; fewer than half are social bumblebees or honeybees
Solitary bees are often more efficient pollinators than honeybees for many plant species
Ground-nesting mining bees need bare or sparsely vegetated soil — increasingly rare in tidy gardens and urban areas
Many solitary bee species have very specific flower requirements — wildflower diversity is essential
Pesticide exposure kills solitary bees at the same sub-lethal doses that harm honeybees

Welfare Considerations

Solitary bees have shorter lifespans than social bees and limited ability to survive environmental disruption. A female mason bee building her nest tube has a single reproductive season — loss of nesting sites or food plants in that season ends her reproductive contribution permanently. Their welfare and conservation are inseparable from wildflower habitat availability.

What You Can Do

Install bee hotels with appropriate diameter tubes for mason and leafcutter bees
Leave areas of bare ground in gardens for mining bee nesting
Plant diverse native wildflowers with different bloom times to support specialist bees
Support Bumblebee Conservation Trust and Buglife pollinator habitat projects
