Typical swarm locations
Collectors regularly attend swarms in the older terrace garden remnants and hedgerow oaks of the Fore Street and Plain-an-Gwarry conservation areas, on the heather and gorse heathland of the Wheal Peevor and Great Flat Lode mining margins, along the valley alder and sallow margins of the Red River towards Portreath, and in the chimney stacks and granite eaves of the older mining-town properties.
