Ghost White Mysis Shrimp

Mysis Shrimp · Nymph

A ghost drifting through cold, clear water

A translucent white Mysis Shrimp on a size 16 scud hook, tied to drift for trout below reservoir dams.

A pale mysis shrimp fly with black eyes, a segmented clear back and a soft pink glow at the thorax. It is built from white Antron, clear Thin Skin and a monofilament rib over a bronze scud hook.

On the water

A nymph fly drifting above a cobble streambed

Almost see-through at first glance. A clear segmented back, white legs fanning underneath, two black eyes up front and a blush of pink where the gut sits. Behind it, copper autumn leaves and a river running glassy and green.

Mysis wash out of reservoirs and tumble helpless through the tailwater, so this one wants a dead drift. Fish it under an indicator through seams and soft runs, close to the bottom, and let the current do the work.

Clear Thin Skin makes or breaks the look. Cut a strip the width of the hook gap, tie it in tight at the bend, and pull it forward snug over the body so the monofilament rib can press clean segments into it.

Tippet

Leader
Nine feet, with fluorocarbon tippet to get it down
  • Rig on 6X or 7X fluorocarbon tippet; clear tailwater rewards a fine, quiet leader.
  • Add split shot above the fly and set the indicator about one and a half times the water depth.
  • Dead drift first; a slow lift at the end of the swing can show the legs moving.

How to tie it

The steps, from first wrap to whip finish (12)
  1. Mount the hook in the vise and start the thread behind the eye, wrapping a short base back toward the bend.
  2. Tie the black mono eyes on top of the shank just behind the hook eye with tight figure-eight wraps.
  3. Tie in a sparse bunch of white Antron yarn at the bend as a tail, about half the shank length past the bend.
  4. Tie in the clear monofilament rib at the bend along the underside of the shank.
  5. Tie in a strip of clear Thin Skin at the bend, shiny side down, extending back over the tail.
  6. Dub a slim white Antron body forward to about two thirds of the shank.
  7. Dub a small ball of pink Antron for the thorax spot just behind the eyes.
  8. Tie in a short bunch of white Antron yarn under the thorax as legs, reaching back to mid-body.
  9. Pull the Thin Skin forward over the body and thorax and tie it down behind the eyes.
  10. Wrap the monofilament rib forward in even open turns over the Thin Skin, about six segments, and tie off.
  11. Trim the excess Thin Skin and rib, then build a small neat white thread head in front of the eyes.
  12. Whip finish and add a thin coat of head cement.
Proportions (5)
  • Tail extends about half the shank length past the bend.
  • Body stays slim, roughly the thickness of the eyes.
  • Pink thorax spot covers the front third of the body.
  • Legs reach back to about mid-body.
  • Thin Skin strip as wide as the hook gap.
Tips (4)
  • Pick the Antron dubbing out a little before wrapping so the body stays sparse and light passes through.
  • Stretch the Thin Skin slightly as you pull it forward; it lies flatter and the segments look sharper.
  • Keep thread wraps few and flat under the body so no bulk shows through the clear back.
  • Comb the legs and tail with a dubbing brush after the whip finish to separate the fibers.
Common mistakes (4)
  • Overdressing the body hides the translucency; use half the dubbing you think you need.
  • Crowding the eye leaves no room for the head; stop the thorax a few thread wraps behind the eyes.
  • Uneven rib spacing breaks the segmented look; count your turns and keep the gaps equal.
  • A pink thorax that is too big reads as a bright bead; keep it a small, soft spot.
