Eyes Two red plastic craft beads (2, matched for size and shape)
Tail Olive marabou (a thin sparse bunch)
Body MS Nymph Dub in damsel brown (small pinches)
Hackle Olive, grizzle or ginger cock hackle (1 feather)
Rib 4-5lb nylon monofilament (one short length)
How to tie it
Pick two red plastic craft beads that are close in size and shape, these craft beads vary a lot, and slide both onto a size 10 barbless nymph hook. A long shank hook is used because the two beads take up so much of the front.
Mount the hook, start the thread and build a bump of wraps behind the beads to lock them in place so they cannot move. You can superglue them as well if you want.
Using the tag end to keep the wraps even, run a thread base back to the bend.
Select thin long marabou fibres for the tail and use them sparsely. Wet your fingers and roll the ends up. It secures the bunch and makes it much easier to tie in.
Measure the tail to about one hook length, snip it a little shorter, re-bundle it and tie it in with a pinch wrap. Up between the fingers loose, then down, then up and down again. Add one wrap behind the tail to cock it.
Tie in a short piece of 4-5lb nylon for the rib right at the base of the tail. Make it very secure, as nylon is slippery. It only has to hold the hackle down, so it does not need to be strong.
Wax the thread with Loon Low Tech Swax and dub on small pinches of damsel brown MS Nymph Dub. Do not roll it too tight. The dub has rubbery legs and bits in it and you want the body spiky, to add to the movement.
Wind the dubbed body forward, keeping it quite slim, up to the back of the beads. Pinch off any excess and add a little more dubbing to finish it neatly.
Choose a hackle with reasonably long but not enormous fibres and strip it back to the point where the colour starts. Tie it in behind the beads with the concave side facing backwards.
Using hackle pliers, wind the hackle backwards down the body to the tail. The same way you would tie a woolly bugger, only front to back.
Take the nylon rib, being careful not to catch the tail, and go twice around tight at the rear to trap the hackle stem, then wind it forward in the opposite direction to the hackle, wiggling and zigzagging so it traps the stem and not the fibres.
Wrap the thread around the nylon a couple of times and pull tight, wind on again and secure it hard. Nylon needs the extra wraps. Snip the nylon and the hackle tip off.
Put a pinch of dubbing on to cover the thread behind the beads, add superglue to the thread if you have it, and whip finish.
