Typical swarm locations
Collectors regularly attend swarms on the limestone grassland margins of Rodborough Common and Selsley Common, in the old orchard gardens and dry-stone wall boundaries of the Bisley and Slad valley villages, in the restored millpond and canal-side vegetation of the Stroud valleys waterway, and in the chimney stacks and stone-slate roof voids of the older Cotswold-stone terrace properties.
