Typical swarm locations
Collectors regularly attend swarms in the old lime and horse chestnut in the Community of the Resurrection grounds, in the garden trees and stone-wall crevices of the older residential roads around Northorpe and Hopton, in the hawthorn scrub along the Calder and Calder and Hebble Navigation towpath, and in the roof voids and chimney stacks of the Victorian and Edwardian mill-town terraces.
