Ultra suede or leather Tan carapace (1 tail strip)
Foam Gray foam (optional underbody)
Rubber legs Black ostrich herl (2-4)
How to tie it
Start thread at the bend and tie in a thin ultra-suede tail one to two shank lengths long, so it trails and steers the fly.
Optionally tie in a strip of foam along the top for buoyancy.
Spin a clump of deer hair around the shank, pack it tight, and repeat forward in 2-3 clumps, packing hard each time to build a dense body. Add a rubber leg on each side as you go.
Leave a small clear space behind the eye and whip finish.
Trim the spun hair to a rounded mouse-body shape, flat on the bottom and domed on top, leaving a few longer guard hairs at the front as a face.
Add a drop of cement at the thread head to lock it.
