Typical swarm locations
Collectors handle swarms in the sycamore and lime trees of the town centre on West Street and Dark Street, along the Wye riverside margins and the Elan Valley reservoir path margins at the visitor centre, in the older stone and render properties of the market town streets, and in chimney stacks and eaves of the smaller slate-roofed stone cottages and hill-farm steadings of the surrounding Elan valley parishes.
