Lots of Duke of Burgundy on the wing here with at least fifty seen. This was a real treat for me as I've only ever seen them in their Somerset sites where five is the highest number I'd seen.
Duke of Burgundy - Hamearis lucina
Green Hairstreak - Callophrys rubi
Small Heath - Coenonympha pamphilus
Early Purple Orchid - Orchis mascula
Also available in pink and white.
Fly Orchid - Ophrys insectifera
The only Fly Orchid with a flower open was this strange coloured one with very little pigmentation.
White Germander Speedwell - Veronica chamaedrys
Bur Chervil - Anthriscus caucalis
Round-leaved Cranesbill - Geranium rotundifolium
Grass Eggar Caterpillar - Lasiocampa trifolii
Mother Shipton - Euclidia mi
Heath Dog Violet - Violet canina
Adderstongue Fern - Ophioglossum vulgatum
An unusual example with a split stalk looking even more like an adder's tongue.
