Spider (I think)

I was walking around one of the local lakes today trying to capture a bug of some sort but something I haven't captured before.
There were thousands and thousands of Damselflies and I already have too many photos of them filling up my disc space. However I couldn't resist taking a few of them. Then there were lots of Bees. I love Bees but I also have loads of photos of them.
I was passing some stinging nettles and I noticed a leaf that looked like it had some debris on it but on closer inspection it was a creepy crawley of some sort. It wasn't untill I got the photo on the PC that I realised it was a spider of some sort, well it's got 8 legs. I think he was laying in wait for a passing ladybird.
