The first picture is Lousewort (
Pedicularis sylvatica)
The second is Common Yellow-sedge (
Carex viridula ssp.
oedocarpa) with some sort of Cranefly sprawled over it
Personally I like the dragonfly picture except for the mess of twigs on the righthandside, so thats more a criticism of where the dragonfly chose to sit, rather than on the performance of the lens.
