Last year (it was in June I believe) I was fishing a local river when I noticed that the fish were taking something just below the surface. I tried a few favourite patterns, but they didn't produce much.

At one point, I moved into shallower water, and that's when I noticed that my legs were covered in hundreds of little dark caddis flies. Although I switched to an Elk Hair Caddis, there were still few takes (as I said, the feeding seemed to be just below the surface).

Can anyone suggest:
1. a black caddis dry pattern (or is that as simple as turning everything in an Elk Hair Caddis pattern black)?

2. a caddis emerger that might match this hatch?

Thanks,
Andrew
