Taking fish on dry flies is great fun, but as I learned the hard way on a recent trip when my friend Jirka totally outclassed me, trout truly do consume most of their food below surface.
I was fishing a dry caddis imitation and enjoying seeing the occasional strike on surface, while he was fishing a wet caddis and having fun getting 10 fish to 1 mine.
Once I got home I sat down and tied these simple wet caddis flies to do better the next time.
It is a very simple tie, the key factor being wing of Australian Possum hair. It has a peculiar wavy but coarse look and once wet is very mobile. I hear that it is commonly used in many Australian fly patterns.
