Typical swarm locations
Collectors attend swarms in the oilseed rape and raspberry field margins of the Easter Ross plain, along the Cromarty Firth sea-aster shore, on the Fyrish Hill heather fringe to the west, in the older stone properties and harbour-front buildings of Invergordon, and in the garden walls and outbuildings of the farming steadings along the Invergordon to Tain road.
