Typical swarm locations
Barnet collectors regularly attend swarms in the lime and chestnut avenues of Monken Hadley Common and Hadley Wood, in the mature garden trees and rose hedges of the older Barnet High Street and New Barnet residential streets, in the scrubby hawthorn and elder of the Pymmes Brook corridor, and in the roof voids and chimney stacks of the inter-war semi-detached properties of Friern Barnet and Oakleigh Park.
