Current UK Species Action Plan
Nests in cavities within a variety of substrates, including drystone
walls and holes in dead wood, in full sun. There is a
close association with bird's-foot trefoil.
Declining - Agricultural intensification of upland herb-rich
pastures, destruction of dry-stone walls and inappropriate
management of pasture woodlands.
