Typical swarm locations
Collectors attend swarms in the veteran lime and sycamore of Gean House grounds and Alloa Park, on the scrub and elder of the Black Devon corridor west of the town, in the eave voids and chimney stacks of the older sandstone properties around Mar Street and Broad Street, and on the Forth riverside path to Tullibody where hawthorn hedges and riverside willows are reliable swarm sites in May and June.
