I was now pleased that my decision to call in here was successfull. I found it difficult to get any shots of it, especially with one hand. Now the other sheet of refugia was next to it. I very carefully and slowly lifted that one which isn't easy using the end of one of my crutches, if there was anything under there I didn't want to startle it. After raising it about half half was up I found another one. I took my camera and with delight I again fired off some shots, what I got was unknown at this time. The Adder then slithered off into the undergrowth and that is when I called it a day.
Out of the photo's I took the ones below are about the best of the bunch.
** I have been corrected by Greenie that the adders are not females, but males. Thanks for that.**
P.S. On the way back to the car I saw the following moths, and I have spent ages trying to i.d them. I have narrowed it down to a couple. I looked them up on the UK Moth website and I have now confused myself, and it is doing my head in. I think the first one is a one of the Carpet Moth species, possibly a Silver Ground Carpet (see below)
