The 270 species of solitary bees in the UK receive far less attention than honeybees despite being critical pollinators. Their welfare depends on undisturbed nesting sites and diverse floral resources.
Solitary bee welfare is primarily shaped by nesting site availability and floral resource diversity. Females unable to find suitable nesting sites lose the season's reproductive opportunity, representing significant individual welfare cost in terms of exhausted searching behaviour. Pesticide exposure causes sub-lethal effects including impaired navigation and reduced learning ability - affecting individual welfare without causing immediate death. Ground-nesting species are particularly vulnerable to soil management. Garden interventions - bare earth patches, bee hotels, diverse flowering plants - directly improve the welfare prospects of individual solitary bees.
