Loopwing Caddis Emerger

I copied this pattern that a sport gave me once. I do not know where in originated other then from the guy I got it from. It is similar to the Iris Caddis. This is a real good pattern for use during a Caddis hatch. It can be used alone but is more visible if used as a trailer with a larger dry fly. 

Hook - dry fly size 14-18

Thread - Tan Veevus 16/0

Trailng shuck - Tan emerger yarn

Wing - Tan emerger yarn

Body and thorax - Tan dubbing
