Typical swarm locations
Collectors attend swarms in the Gryfe gorge woodland of alder, willow and sycamore, in the garden lime, apple and ornamental cherry trees of the Victorian villa belt on Kilmacolm Road and Station Road, along the himalayan balsam and elder margins of the Gryfe riverbank through the village, and in chimney stacks and eave voids of the older stone villa and cottage properties.
