Typical swarm locations
Collectors regularly attend swarms in the older garden remnants and lime trees of the Market Place and Wide Bargate conservation areas, along the Witham riverside willows and dyke-side willowherb margins at Fishtoft and Skirbeck, on the saltmarsh and reed-bed margins of the Haven estuary, and in the chimney stacks and eaves of the older Georgian and Victorian town-centre properties.
