How to tie it
Slide the gold bead to the eye, mount the hook, and lay 6-8 wraps of lead behind the bead, shoving them up into the bead socket.
Start thread and at the bend tie in two short, splayed white poly tufts. These are the larva's rear spiracles, so keep them stubby, no more than a hook-gap long.
Tie in the mono rib at the bend.
Dub a fat, tapered body forward to just behind the bead. Fullest in the middle like a real crane fly larva.
Counter-wrap the mono rib forward in 5-6 evenly spaced turns to segment the body and add durability.
