Typical swarm locations
Mudeford Quay sea-lavender and coastal scrub on the harbour edge attract clusters on sunny June days. Stanpit Marsh reedbeds and saltmarsh scrub on the Christchurch Harbour shore provide late-season coastal forage. Hawthorn and elder in the Purewell and Wick lane hedgerows are a spring swarm site. Older coastal cottage chimney stacks and beach-hut outbuildings are the most commonly reported cavity swarm locations.
