How to tie the Critter Worm Stillwater Fly


This incredibly brightly-coloured trout fly is a killer for stillwater fishing.

Although it doesn't really imitate any creature in the natural world, this pattern is a deadly trout taker.

It is a sinking pattern that can be fished quite deep, and because of the brightly coloured materials used it can still be spotted by any nearby trout in the dimly lit water.

The Critter Worm isn't a very complex pattern to tie, therefore it's a great one for beginners to trout fishing.

Here's how it's tied...

Hook: Competition size 12 or wide gape size 10

Thread: Fuschia pink Glo-Brite floss 

Beads: Gutterman seed beads (dark fuschia pink)

Legs: Fuschia pink Flexi-Floss 

Tail: Fuschia pink marabou 

Butt: Fuschia pink Glo-brite floss


1. Take a length of Flexi-Floss and feed both ends through the centre of the glass bead. Slide bead over hook-point and fix hook in the vice.

2. Push bead up hook shank so that it sits snugly against the eye. Draw the ends of the Flexi-Floss through the bead to make two, long legs.


3. Run thread on behind bead to stop it moving back down the shank. Take the other two ends of the floss and apply a single, overhand knot.

4. Apply a layer of the pink thread along the shank then cast it off. Add another two glass beads before fixing the hook back in the vice.


5. Push the two extra beads hard up against the front one. Reapply thread, using overlapping turns to create a pronounced taper.

6. With the beads now fixed in place, continue winding the thread to the bend. There, catch in a small pinch of pink marabou, to form the tail.


7. Secure the tail with tight thread-turns then apply more turns to complete the tapered rear section to the body.

8. Cast off the tying thread with a whip-finish made at the read of the last bead. Apply two coats of clear varnish to protect the thread.


9. Take a third strand of Flexi-Floss and apply an overhand knot. Place floss over body drawing it tight between the first and second beads.
