I think - it seems to fit the description in my wild flower book anyway. Had a lovely walk around Soudley Ponds and saw lots of wildlife. The most fascinating was a small web on a tree trunk with a hole in the middle. It appeared to have a piece of grass pulled into the hole. When I touched it a spider came out - clever spider setting a trap like that!
I've fiddled about (technical term) with this photo using the basic edit on the laptop and liked this version better.
