Hi David,
I was walking round with the warden this morning (must have just missed you) and the general thinking is that the emergence of Large Blue and flowering of its Wild Thyme foodplant are very closely linked, being influenced by the same factors (such as soil temperature). Collard has a very clayey soil compared to other Large Blue sites, and so stores far more water, this in turn lowers the soil temperature and retards the development of Large Blue larvae and Wild Thyme, leading to this amazingly late emergence. This is very apparent on the site with only your Large Blue and a small amount of Thyme in flower, nice Marbled White by the way
