We followed the path past the Kingfisher screen and up the slope where the bordering vegetation included patches of birds foot trefoil, thistles and vetch and which provided lucrative sightings. One of the delights was this brown butterfly, but on consulting the guides the brown upperwing and underwing marksings lead me to think this is a female Common Blue (Polyommatus icarus).
And here's a male Common Blue, 15 or so metres away from where I spotted the female not a great pic but good enough to illustrate the difference in upperwing colour between the sexes.
A field of ox eye daisy, buttercups and grasses near the spot where we spotted the Common Blues.
A couple of metres away, my first Small Skipper (Thymelicus sylvestris) of the year, the black mark on its upper forewing indicate a male, the mark are the glandular scent scales or androconia that produce an odour to attract females.
Thanks to Pete for confirming the ID of this one. A daytime flying moth, a Silver Y (Autographa gamma) with the distinctive Y on the upperside of the forewing, which feeding here on a clover flower.
Striking clumps of purple orchids grew at intervals between the path and the stream. Not knowing one orchid from another I won't even hazard a guess but I would guess that they're a popular source of nectar for the many insects in the area.
