Typical swarm locations
Collectors attend swarms along the Water of Leith walkway banks and the elder and hawthorn scrub at the Balerno and Juniper Green sections, on the Pentland Hills gorse fringe above the village, in the garden walls and outbuildings of the older village core around Balerno High Street and Marchbank Road, and in the eaves of the 1970s estate houses at the hill edge.
