Typical swarm locations
Collectors attend swarms in the dune-slack grassland and scrub margins of Merthyr Mawr NNR, in the walled and hedged gardens of Newton village and the older Porthcawl seafront terraces, along the bramble of the coastal path between Rest Bay and Sandy Bay, and in the eaves and cavity walls of the guest houses, bungalows, and modern housing throughout the resort.
