Typical swarm locations
Collectors handle swarms at the arboretum and specimen trees at Kilmun, in the garden hedges and rhododendron policies of the Victorian villa streets on the hillside above the Clyde, in the gorse and heather scrub on the hill ground above Kirn, along the Holy Loch foreshore scrub, and in chimney stacks and eave voids of the Clyde-front Victorian hotels and terraces.
