Typical swarm locations
Collectors regularly attend swarms in the older terraced properties and churchyard trees of Swinton centre, along the Dearne Valley riverside willows and wetland margins at Old Moor and Broomhill Flash, on the brownfield and reclaimed spoil banks of the former colliery sites between Swinton and Mexborough, and in the chimney stacks and eaves of the older Victorian mining-town properties.
