Typical swarm locations
Collectors in Nailsworth regularly attend swarms in the beech and sycamore woodland along the Nailsworth Stream corridor and the escarpment above Watledge, in the walled gardens and stone-built terraces of the town-centre mills and Chestnut Hill district, on Minchinhampton Common where gorse and scrub provide ideal clustering sites, and in the stone chimney voids of the older cloth-mill conversions along the valley floor.
