Typical swarm locations
Collectors attend swarms in the mature walled gardens and lime-avenue streets of the Alverstoke conservation area, along the sea-lavender saltmarsh margins of Portsmouth Harbour and the creek edges near Haslar, in the ornamental grounds and old boundary walls of the Royal Navy hospital site, in the garden shrubberies of the Stokes Bay and Lee-on-the-Solent hinterland, and in the Victorian terrace rooflines and chimney stacks near Gosport town centre.
