Typical swarm locations
Collectors here regularly attend swarms in the canal-side sallow and willowherb of the Grand Western Canal towpath, in the garden trees and old boundary walls of the Fore Street and Gold Street conservation areas, in the orchard-remnant gardens of the outlying villages of Bickleigh and Butterleigh, and in the chimney stacks and cob-wall roof voids of the older town-centre properties.
