Umbrella Western Green Drake Dun

Largest in a series of Mayfly Dun patterns I tie using the Umbrella hooks. I tie the extended bodies using 8lb monofilament wrapped with whatever dubbin material I use for the fly. Main difference I've made has been the hackle - where I used to wrap it around the vertical post, I now figure-8 wrap it around the thorax. Believe it or not it seems to float much better.

Hook: Large Umbrella
Thread: Olive
Abdomen: 8lb test monofilament wrapped with light olive dubbin
Abdomen overwrap: Pheasant tail fibers, light side up
Ribbing: Danville's gold fine wire
Wing: Slate gray CDC, doubled
Tail: Green dyed Elk fibers
Hackle: Olive, figure-8 tied around the thorax

Note: Western Green Drakes have massive wings and they are splayed for drying as they float on the water. I use the butt ends of the Pheasant tail fibers and pull them back between the wings and then again forward to tie them off.
