Typical swarm locations
Pontefract collectors attend swarms in the limestone grassland margins of Pontefract Castle and the adjacent castle ruins park, in the lime and horse chestnut avenues of Pontefract Park and the older Baghill and Tanshelf residential streets, along the bramble and elder scrub of the colliery reclamation land towards Glasshoughton, and in the chimney pots and older Yorkshire stone terrace roof voids of the market town centre.
