Improved Chaos Hopper

March 20, 2010

Chaos HopperPATTERN DESCRIPTION:

How To Tie The Improved Chaos Hopper. The Improved Chaos Hopper created by Craig Matthews of West Yellowstone, is a great late-summer realistic hopper pattern.  This foam hopper has the right silhouette and just enough wiggle with its rubber legs to fool any trout late into the summer.  I really like the Improved Chaos Hopper in smaller sizes like 10-14’s in its original cocoa color, or even tan, goldenrod or peach colors.  Whenever I’m fishing low, gin-clear waters like those found in Yellowstone Park in August and September, or even the big rivers like the Big Horn or Yellowstone River where the fish have seen size 8-12 hoppers time and time again, I like to switch things up by tying on a size 12-14 Chaos Hopper. This pattern is easy to tie, very durable and buoyant, and looks and fishes great in extra-small sizes.  Tie some up, I think you’ll be pleased.

MATERIALS NEEDED:

Hook: Dai-Riki #280 sizes 10-14

Thread: UTC Ultra 140 or 70 Denier brown thread.

I use the UTC 140 denier for the larger size foam hopper patterns, and the 70 denier for any foam pattern size 14 and smaller.

Foam: 2mm cocoa craft foam.

Wing: Tan Crinkled Z-Lon

Legs: Square rubber legs from Blue Ribbon Fly Shop sold in tan, yellow and green.  Pattern looks pretty good with med. round legs also.

Post: 2mm orange or yellow foam.

Improved Chaos Hopper

Step 1

Step 1: Cut a strip of 2mm craft foam.  Strip of foam should be width of gap of hook and 2″ long.

Step 2

Step 2: Trim foam strip to a taper as shown.  Taper should be about half the length of the hook.

Step 3

Step 3: Build a thread base on the front 1/2 of the hook only.  I build a 3 layer thread base, then stop thread at point shown above. Right where the thread is hanging is where the foam strip is going to be tied in.

Step 4

Step 4: Pierce a hole in the foam strip as shown.  The hole should be placed a hook length from the tapered end of the foam strip and centered.

Step 5

Step 5: Remove hook from vise and slide foam strip onto hook through the pierced hole made in the previous step.

Step 6

Step 6: Slip foam strip up to the thread base. Tie-in point is where thread is hanging in Step 3. Bind foam strip on top of hook with 2-3 firm thread wraps.

Step 7

Step 7: Lightly stretch the strip of foam extending over eye of hook.  Pull strip of foam against eye of hook.  The hook eye should leave a mark in the foam.  Use a bodkin and pierce a hole in the foam as seen in photo above.

Step 8

Step 8: Tie in z-lon overwing.  For the overwing, you will want two strands of z-lon extending towards the tail of the hopper.  Either tie in two separate strands of z-lon at tie-in point above or double a single strand of z-lon over itself to form a two-strand z-lon wing. Trim wings to length of foam hopper body.

Step 9

Step 9: Form bullet head of the hopper.  Push eye of hook through the hole made in Step 7. Apply super-glue to exposed thread base.

Foam Flies

Step 10

Step 10: Fold over foam strip to form a bullet head and cinch down foam with 2-3 firm thread wraps.  Notice there is no gap between bullet head and hook eye.  Cut off remaining foam strip as shown above.

Step 11

Step 11: Make a thread base for the legs.  Use 5-6 wraps of thread for the base. Notice that most of the hopper is all tied in at the same spot on the hook, therefore, keep thread wraps to a minimum.

Rubber Legs

Step 12

Step 12: Make the hopper legs by tying an over-hand knot in a 2″ strand of rubber leg material.  Repeat for other leg.

Step 13

Step 13: Tie in legs of hopper as shown.  Legs should be parallel to body and the knot of each leg should extend to bend of hook.

Step 14

Step 14: Bind down legs with 5-6 wraps of thread.

Foam

Step 15

Step 15: Cut a thin strip of 2mm yellow foam for the post.  The foam strip should be slightly narrower than the head of the hopper as shown above.

Step 16

Step 16: Bind down foam post with 2-3 firm thread wraps.  Notice tie-in point is right in the middle of thread base. Whip-finish at this point. Foam post should extend to barb of hook.

Step 17

Step 17: Trim remaining foam post as shown in photo above.

Step 19: Trim legs to desired length.  I trim the front legs to hook length, and portion of legs below the knots about half the length of the hook.

    The chaos is a great hopper. I’m looking forward to tying some of these in our flying club over the winter.

      It’s a fine hopper. I tied some, and they are very good to catch tilapias(Tilapia rendalli), apaiaris (Astronotus ocellatus), and larger size, the matrinchãs (Brycon amazonicus/Brycon cephalus).
      Thanks for these step-by-step.
      Lines up!
