Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the High Street and Church Street conservation areas, along the Nene riverside willows and watermeadow margins at Stanwick Lakes and Irthlingborough gravel pits, in the old orchard and allotment remnants of the Victorian boot-factory suburb fringe, and in the chimney stacks and eaves of the older ironstone and brick properties.
