Typical swarm locations
Collectors regularly attend swarms in the older garden and terrace remnants of the Trelowarren Street and Basset Road conservation areas, on the heather and gorse heathland margins of the Carn Brea and Basset Mines heritage site, along the valley willows and alders of the Penponds stream towards Troon, and in the chimney stacks and granite eaves of the older mining-town Victorian properties.
