Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Tuesday Market Place and King Street conservation areas, along the Great Ouse riverside willows and reed-bed margins at the Nar and Fisher Fleet, on the saltmarsh and sea-lavender margins of the Wash shore at Snettisham, and in the chimney stacks and eaves of the older medieval and Georgian town-centre properties.
