Typical swarm locations
Collectors regularly attend swarms along the Shropshire Union Canal towpath hawthorn and elder scrub, in the rough grassland and bramble margins of Rivacre Valley and Whitby Park, in the older garden trees and allotment hedgerows of the inner residential streets, and in the chimney stacks and eaves of the older semi-detached and terraced properties on the Overpool and Whitby Road corridors.
