Typical swarm locations
Collectors attend swarms along the River Nevis himalayan balsam and willow margins from the town to the gorge, in the Caledonian Canal bank scrub and elder between Fort William and Banavie, on the lower Ben Nevis bilberry and heather slopes, in the garden walls and outbuildings of the older High Street and Fort area properties, and in the eaves of the lochside Victorian and inter-war bungalows.
