Typical swarm locations
Collectors in Potters Bar regularly attend swarms in the mature lime trees and sycamore of the Darkes Lane and Mount Pleasant conservation area, in the beech and oak boundary woodland of Hadley Wood at the Bentley Heath fringe, in the privet and pyracantha hedges of the newer estate gardens on the Cuffley and Northaw roads, and in chimney stacks of the older Edwardian and inter-war properties near the station.
