Typical swarm locations
Collectors in Sedgefield regularly attend swarms in the mature lime and horse chestnut of Hardwick Hall Country Park, in the walled gardens and garden hedges of the older townhouses on Front Street and West End, in the parkland trees and orchard margins at the town edge toward Fishburn and Mordon, and in the chimney stacks of the older colliery-era brick terraces in the surrounding villages.
