Typical swarm locations
Collectors attend swarms in the sycamore and lime trees of the castle grounds and St Aidan's churchyard, in the stone wall cavities and old property roof voids of the conservation village, along the gorse and blackthorn coastal scrub on the track to Harkness Rocks and Budle Bay, and in the dune grassland margins and hedgerow hawthorn on the farmland lanes leading south towards Seahouses.
