Typical swarm locations
Collectors regularly attend swarms in the old orchard and walled-garden boundaries of the Tavistock Abbey ruins and Bedford Square, in the riverside alders and willows of the Tavy below the town, on the bilberry and gorse moorland margins of the Dartmoor edge above Whitchurch and Peter Tavy, and in the chimney stacks and granite-walled properties of the Victorian town centre.
