Typical swarm locations
Collectors attend swarms on the oilseed rape field margins and hawthorn hedgerows of the farmland between Bathgate and Linlithgow, on the Bathgate Hills heather and bilberry SSSI above the town, in the Polkemmet Country Park sycamore and hawthorn woodland, and in the older stone eave and chimney voids of the residential streets around North Bridge Street and Hopetoun Street.
