Typical swarm locations
Tamar and Tavy creek-side oak and ash woodland margins at Warleigh Point and Tamerton Lake produce spring swarms in the streamside canopy. Hawthorn and blackthorn lane hedges on the Weston Mill Lake approach are a reliable late-April gathering site. The churchyard lime and elder at St Mary's church on the village green is perhaps the most noted local swarm location, flowering in June and attracting prime swarms each year. Older stone-built farm and cottage outbuildings above the creek are the most frequent cavity swarm sites.
