Typical swarm locations
Collectors regularly attend swarms in the older lime trees and garden remnants of the Cathedral Quarter and Friargate conservation areas, along the Derwent riverside willows and watermeadow margins at Darley Park and Borrowash, in the old parkland and walled garden remnants of Markeaton Park, and in the chimney stacks and eaves of the older Victorian and Edwardian city-centre properties.
