12.45 - 13.30. Unusual conditions for the North Wilts Downs today - hardly and wind at all. AB out in good numbers, decorating the hillside like jewels when the sun went in, and scrapping over the few nectar sources when it was out. Is there a more complementary pairing in nature than an AB and Carline thistle? (OK, I'll give you ChB and Carline thistle!). Quite a few under-sized individuals, including one half the normal size with unusual markings, missing the ring of black spots on the hindwing.
