I asked in tips and tricks and got one reply so I'll try here. I haven't done much on zebra midges and wonder how you fish them? Under a caddis or with a nymph?
Another method to fish the mighty zebra is under a foam stick on indi. When fish are sipping midges, very subtle takes that is, I put one 18-24" down off an indi or dry. Works very good.
The oldest midge fishing suggestion is to fish where the trout are. If they are on the bottom, fish them with a heavier nymph on the bottom (most common way for me). If you see mid level flashes fish them in the middle - usually dry dropper for me. If the fish are in the surface, grease em up and fish them in the film. This is where I normally cut off the Zebra midge and put on an Al's Rat.
