Today I counted 25 Common Blue butterflies on the signal box bank alone, plus many more else where on the site. Other species of note seen today include: Holly Blue, Small Copper, Cinnebar, Burnett Companion & Green Carpet (pictured), plus caterpillars of Small Tortoiseshell and Burnett. There were also lots of damselflies: Common Blue, Blue Tail, Banded Demoiselle and Red Eye, even some flying in tandem over the small gravel pit.
There was also a Cuckoo present on site all afternoon, on the fence posts around the deep pit.
