Typical swarm locations
Collectors along the Southend seafront corridor handle swarms in the mature sycamores and limes of Chalkwell Park and Priory Park, in the Victorian chimney pots of Westcliff, in garden hedgerows towards Leigh-on-Sea, and on the saltmarsh boundary at Two Tree Island. Leigh-on-Sea's weatherboarded fishermen's sheds and boat-shed eaves are occasional swarm locations too.
