Typical swarm locations
Collectors regularly attend swarms in the orchard and garden remnants of the Canon Square and Bank Street conservation areas, along the Avon riverside willows and watermeadow margins at Melksham Forest and Berryfield, in the hedgerow oaks and scrub of the Spye Park lanes towards Derry Hill, and in the chimney stacks and eaves of the older Victorian and Edwardian town-centre properties.
