As far as insect activity goes there were a few straggling Hendricksons coming off, but that hatch peaked a week or two ago and should be all but over. I did not observe any caddis activity (at or above the surface), but I know there was some earlier in the week. The only other insects were a few small stone flies crawling about on mid-stream rocks. What are these fish taking this fly for??? ( I have a guess)
There may have been a behavioral drift of green rock worms (Rhyacophila) occurring. I was snagging these little buggers left and right. In my opinion this fly bears little resemblance to the natural but I guess the fish disagree. I even went as far as to imitate the obviously prevalent caddis larva with one of my rock worm patterns that did a better job "matching the hatch".
