Hook: TMC 200R in size 8 weighed with wire on the front half
Thread: UTC 140 Black or Orange
Tail: Golden brown hares mask
Body: Wapsi Crawdub...color to suit. I'm partial to burnt orange, rusty brown, brown olive,and brick. Suggestion: Buy all 12 colors and mix the shades to get exactly what you want.
Wing Case: Flat black Diamond Braid folded overThorax: Brown hen hackle pulled over Wapsi Crawdub tied in using a dubbing loop (split the thread). As an alternative tighten up the thorax dubbing and palmer the hackle.
There are lots of different renditions of this pattern....click here for one I like.
