Typical swarm locations
Collectors regularly attend swarms in the sycamore and lime of the Main Street and Corbridge churchyard, along the River Tyne riverside willows and hawthorn scrub towards Riding Mill and Bywell, in the mature garden trees and orchard edges of the sandstone farmsteads and village properties between Corbridge and Great Whittington, and in the chimney stacks and eaves of the older sandstone houses and Victorian terraces of the town.
