Typical swarm locations
Collectors attend swarms on the Loch of Harray shore vegetation and the wetland edges of the drainage ditches bordering the loch, in the older stone farmhouse gardens and their mature trees along the Finstown-to-Dounby road, in the farm building eave gaps and stone dykes of the croft land in the interior of the parish, and on the heather and gorse of the central Mainland moorland ridge to the south.
