Wild Common Blue Butterfly Welfare

Common blue butterflies are declining due to habitat loss. Grassland management supporting wild thyme and bird's-foot trefoil provides larval food plants and supports butterfly welfare.

Key Facts

Common blue butterflies depend on bird's-foot trefoil as their primary larval food plant
Short-sward chalk grassland and roadside verges are key habitats
UK butterfly populations have declined significantly since the 1970s
Management including late mowing maintains suitable larval habitat
Urban gardens with clover and other legumes can support common blue populations

Welfare Considerations

Common blue welfare is linked to larval food plant availability. Habitat management that maintains suitable grassland benefits individual butterfly welfare and population viability.
