Typical swarm locations
Collectors regularly attend swarms in the older lime trees and walled gardens of the Cathedral Close and High Street conservation areas, along the Great Ouse riverside willows and watermeadow margins at the Ouse Washes and Littleport, on the dyke-side and fen-edge margins of the Engine Drain and New Bedford River, and in the chimney stacks and eaves of the older cathedral city and Victorian properties.
