Typical swarm locations
Collectors regularly attend swarms in the old orchard and garden walls of the Abbey Terrace and Barton Street conservation areas, along the riverside willows and alders of the Severn meadows at Mythe and Severn Ham, in the meadow hedgerow trees of the farmland lanes towards Bredon and Ashchurch, and in the chimney stacks and timber-framed roof voids of the medieval town-centre properties.
