Eight fresh Walls on Corfe Common transect yesterday. In a normal year I would say second brood, but this year I would say Third brood as the second appeared in July. Hopefully they will have time to develop and overwinter as young larvae @dorsetbutterflies.bsky.social

Its week 23 of the UK Butterfly Monitoring Scheme!
September is here and we're into the last month of the survey. Some summer species may no longer be on the wing, but as we're having a bumper year, keep an eye out for second (or even third) broods of some species.

Not that long ago in August Buddleia's could be covered with Small Tortoiseshells (A urticae, kleine vos). On eBMS transects and 15min counts (www.butterfly-monitoring.net) this butterfly is now restricted to higher elevations or latitudes. Open squares=counted in that period.
