Purple GFA Foam Hopper Tutorial

June 19, 2011

Purple Foam HopperPATTERN DESCRIPTION:

This hopper pattern was created by Walter Wiese out of Parks Fly Shop in Gardiner, Montana.  The GFA Hopper reminds me of the Madam-X, but with a little foam thrown in for floatation and a splash of color.  I really like this hopper in sz. 14 for fishing the smaller creeks here in Montana, but it works equally well on the big rivers like the Yellowstone River and Madison River late in the summer.  This pattern is easy to tie and looks and fishes well in all colors.  Tie some up and let me know how they work.

MATERIALS NEEDED:

Hook: Dai Riki 280, sz 8-14.  The Dai Riki 280 is a specific Hopper Hook that is 2xl long with a curved shank.

Thread: UTC 70 denier for sz. 14, UTC 140 denier sz. 8-12.

Body:  2 mm craft foam.

Wing: Deer Hair.

Legs:  sz. medium rubber legs, barred.

Post:  2 mm craft foam, any bright color such as yellow, white, or orange.

Tying purple foam hopper

Step 1

Step 1:  Wrap a tread base to point of hook.  I usually wrap a 3-5 layer thread base which seems to keep the hopper body from twisting on the hook.

Step 2

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

Step 3:  Trim end of foam strip to a taper.  Next, place foam strip on top of hook as shown above and mark the foam with your fingernail just beyond the hook eye.

Step 4:  Place the foam strip on top of hook. Next, line up the thumbnail mark in foam with the point of hook.  Bind down foam with 5-6 firm wraps of foam.

Step 5:  Advance thread forward, on hook only, about a quarter of the way to eye of hook.  Bind down foam with 5-6 firm wraps of thread.

Step 9:  Advance thread back over foam body to middle of hook eye and point of hook as shown above.  Bind down foam with 2 firm wraps of thread. Notice the three body segments.  The front segment should be a little bigger than the other two segments.   Keeps thread wraps to a minimum here since the rest of the steps will be tied in here.

Step 10:  Tie in stacked deer hair with 4-5 firm wraps of thread.  The tips of hair should extend to tapered end of foam body.

Step 19: After tying in both legs, whip finish fly.  Trim legs and post to desired length.  I usually trim the back legs even with end of tapered body and trim the front legs shorter. For added durability,  apply head cement to the thread around the legs.

    Thanks for the great hopper tying pictures on your site. Although I live in Massachusetts I try to get to Montana / Idaho each year. I have had great success with hoppers with Copper Johns on a dropper. This is my favorite combination.

    Awesome fly man, can’t wait to tie some up and see how they work for me out in VA if we get another hopper hatch soon.

    Excellent instructions and photos- very clear and useful. I will tie some using these instructions and see how the big Cuts and Browns on the Snake River take to them. Expect they will find them juicy.
