On 24/10/18 Brian visited Ballard Down and tells us:
The Swanage Walking Group today walked along the base of Ballard Down, then up Nine Barrow Down near Swanage
There were lots of Clouded Yellows , I counted at least 12 as we walked along. We were all marvelling at how bright and yellow they looked in the sunshine.
Clouded Yellows seem to have done well late this year as many have been reported.
