Typical swarm locations
Collectors attend swarms on the Gryfe Water bankside alder and hawthorn near the Clyde confluence, on the hillside sycamore and gorse above the town on the Clyde Muirshiel Regional Park margin, in the garden trees and eave voids of the residential streets off Princes Street and King Street, and on the brownfield and amenity grassland of the former shipyard and dock sites along the waterfront.
