Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Cathedral Close and Long Causeway conservation areas, along the Nene riverside willows and watermeadow margins at Ferry Meadows and Orton, on the Nene Washes flood-meadow and dyke-side margins towards Whittlesey, and in the chimney stacks and eaves of the older cathedral city and Victorian properties.
