Typical swarm locations
Collectors regularly attend swarms in the older garden and orchard remnants of the Ironbridge and Coalbrookdale conservation areas, along the Severn Gorge riverside willows and alder carrs at Buildwas and Coalport, in the scrub and old meadow margins of the Telford Town Park, and in the chimney stacks and eaves of the older Victorian industrial and ironmaster properties of the Gorge.
