The res is now lower than I have ever seen it so we await the wader passage with great anticipation. On the 18th July there were 6 Common Sandpipers and a single Redshank. Dave had 9 Crossbills on the 25th. There is a huge invasion of Two Barred Crossbills in Scandinavia, so perhaps they will reach our shores soon. This Common Sand was pictured on the outflow filter. There is another outlet below this so the water continues to make its way to Cropston.
I photographed this at Thornton today. I think it is a male Brown Argus. Any experts out there who can confirm this , or is it the brown form of female Common Blue? I think the lack of any spots on the fore wing near to the body is relevant and seems to match the image on page 125 of Butterflies of Brit. and Ireland, Thomas and Lewington.
