Had a couple more small ones, again on the goldhead, and was nearly at the bridge when I saw a few flies heading upstream against the wind. A few turned into a constant stream, so I stopped fishing and managed to snag one in the landing net on its way past. Was surprised to see that it was a small caddis, which I later identified as the grannom.
Waited to see what would happen but, whilst the grey wagtails under the bridge and even the local robin were quick to plunder the new food supply, there were very few rises from any trout. I'd not got any suitable dries with me anyway. However, when I eventually spotted a slashing rise directly opposite me and just past mid-river, I flicked the flies across and "high-sticked" them over the spot. Second try and a trout took the Greenwells spider just as it hit the water.
