Typical swarm locations
Dartmoor edge gorse and heather at Roborough Down and the Bickleigh Down approach attract prime swarms in late April and May. Hawthorn hedgerows on the farming lanes of Woolwell and Widewell are a reliable spring swarm site. Residential garden and boundary elder and sycamore in the Southway Drive streets produce clusters in June. Farm outbuildings and stone walls on the Yelverton approach are common cavity swarm locations on the moor fringe.
