Typical swarm locations
Collectors attend swarms in the Boulevard lime trees and the Hawthorn Avenue sycamore near the West Park boundary, on the hawthorn hedgerows around West Park and the St Andrew's Dock estate margins, in the Humber riverside elder and sea-buckthorn scrub at the Hessle foreshore approach, and in the chimney stacks and closely-packed eaves of the Victorian terrace housing throughout HU4.
