Typical swarm locations
Collectors regularly attend swarms in the older terraced garden remnants and mature shrubs of the Killigrew Street and Arwenack conservation areas, along the creekside alder and sallow margins of the Penryn River and Mylor Creek, on the coastal cliff-top heather and gorse between Maenporth and Swanpool, and in the chimney stacks and granite eaves of the older Victorian and Edwardian seafront properties.
