Typical swarm locations
Collectors attend swarms along the Thurso River willows and bankside elder, in the white-clover and wildflower margins of the Caithness farmland south of the town, on the Dunnet Head coastal heather and sea-campion, in the Norse-plan garden walls and chimney stacks of the older sandstone High Street and Shore Street properties, and in the ling heather moor margins of the county south.
