Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Market Place and Norwich Street conservation areas, along the upper Wensum riverside willows and watermeadow margins towards Beetley and Worthing, in the old parkland remnants of Bylaugh Hall and Gressenhall Farm, and in the chimney stacks and eaves of the older Victorian and Edwardian market-town properties.
