Typical swarm locations
Collectors attend swarms in the garden trees and elder patches of the Stenness properties near the Ring of Brodgar junction on the A965, on the loch-shore scrub of the northern Loch of Stenness shoreline, in the stone farm steading eaves and drystone dykes of the surrounding croft land, and on the flowering willow and meadowsweet of the wet ditch margins between Stenness and Brodgar across the isthmus.
