Weight (optional) .015" lead-free wire or a few turns under the body (-)
Thread Olive UTC 70 denier (-)
Body Olive Sow-Scud / seal's fur blend (e.g. 60% olive with a touch of amber) (pinch)
Hot spot Fluorescent pink (or fl. orange) dubbing, a band in the middle of the body. The pregnant/hot-spot trigger (small pinch)
Shellback Clear/olive Scud Back (Thin Skin or stretch latex) over the top (1 strip)
Rib Fine gold or clear mono, over the shellback (1 strand)
How to tie it
If weighting, add a few turns of lead-free wire along the shank. Start olive thread and run to the bend.
Tie in a strip of clear/olive Scud Back at the bend, pointing back, and a strand of fine gold wire (or mono) for the rib.
Dub the rear third of the body with olive scud dubbing.
Dub a distinct band of fluorescent pink dubbing in the middle third. This is the 'hot spot' (imitating a pregnant female's brood spot); then dub olive again over the front third up to the eye.
Pull the Scud Back forward over the top to form a curved shell and tie down at the eye.
Rib the shellback with 4-5 open turns of the gold wire/mono to segment it, tie off and helicopter the excess.
Pick out a little dubbing underneath for legs, build a small head, whip finish and cement.
For an orange variant, use fl. orange in the hot-spot band.
