Typical swarm locations
Collectors regularly attend swarms in the himalayan balsam and reed margins of the Dearne at Manvers, in the bramble and elder scrub of the former Cortonwood and Wath Main colliery sites, in the mature lime and horse chestnut of the Wath town centre, and in the chimney pots and eaves of the Victorian and Edwardian brick terraces of Church Street and Park Road.
