Typical swarm locations
Collectors attend swarms on the cliff-top limestone grassland scrub and gorse between Pennard and Three Cliffs, in the blackthorn and hawthorn thickets of the Pennard Pill valley, on the garden walls and eaves of the older village properties along Pennard Road, in the churchyard flowering hedges and sycamores, and in the rough gorse and bracken common land at the village approaches.
