Typical swarm locations
Swarms cluster in the sea-buckthorn and bramble scrub of the Links dune paths, on the harbour-wall garden hedgerows, in the amenity sycamore and ornamental cherry of the newer residential estates, and on the sallow and rosebay willowherb of the Blyth estuary reserve margins. Collectors here cover Blyth, Newsham and the Sleekburn coastal plain.
