Body Black (also brown) (2mm closed-cell foam, layered into two lobes)
Legs Black barred rubber legs (3-4 strands round rubber)
Indicator Hi-vis orange (small foam dot)
How to tie it
Mount the hook and lay a thread base across the shank.
Bind a strip of black foam at the bend, cinch it once at mid-shank, then fold and bind again near the eye to form two rounded body lobes.
At the waist, figure-8 in three to four rubber legs so they splay evenly to both sides. Spider legs should be long, roughly one and a half shank lengths.
Take a couple of thread turns to lock the leg splay and keep the lobes distinct.
Add a small hi-vis foam dot on the front lobe so you can track it.
Whip finish under the front lobe and trim leg tips even.
