Improved Thunder Thighs Hopper Tutorial

March 1, 2012

thunder thighs hopper

PATTERN DESCRIPTION: 

The Improved Thunder Thighs Hopper was my go-to hopper pattern last summer in sizes 8-14 in tan, goldenrod, and flesh.  As the summer went on, this hopper seemed to fish better and better.  The realistic silhouette of this grasshopper pattern with its thick foam/rubber legs, bullet-head, large eyes and flashy wing seemed to trigger trout consistently throughout the summer, even in low, clear, late summer conditions.  The realistic legs on this pattern set this terrestrial apart from most other hoppers.  I  also used this fly as part of a hopper/dropper setup with great results.  The fly seemed to always land upright and supported heavy tungsten bead-head copper johns 0r pheasant-tails without a problem.  This fly also works great with a thick poly-wing substituted for the thin foam-wing.  The poly-wing aids in floatation and visibility making this a must-have pattern when fishing from a drift boat.

MATERIALS NEEDED:

Hook:  2 x-long nymph hook.

Thread:  UTC 140 denier.  Great foam tying thread.

Body:  Two-Tone foam with a total thickness of 4mm.

Underwing:  Micro flash, rootbeer color.

Wing:  1mm tan foam.

Legs:  Thinly sliced two-tone foam, super-floss material.  You can knot on any rubber leg material. The super-floss material is very durable and stays knotted to the foam strip with a simple over-hand knot.

Eyes:  2mm black foam strip.

Post:  2mm hi-viz foam strip.

Dubbing:  Tan dubbing of choice.

wrapping thread on hookStep 1:  Form a thread base on hook.  End thread at hook barb.

measure foam body for hopperStep 2:  Prepare a 4mm thick piece of foam body.  Taper end as shown.  Size of foam body should be about gap of hook in width, and twice the length of hook.  Above, I have a pre-cut, two-tone cocoa/tan body (size medium) that is about 2 inches long.

For more detailed instructions on making these foam legs go to the original Thunder Thighs tutorial, steps 10-14.

    I really like the looks of that hopper. Looks fun to tie as well. Thanks for sharing. I’ll be sure to have some of these in my fly box.

      Ben, how have these worked out for you? I like Llano Bugs because they’re easy enough to tie- but this does look fun.

    Nice pattern, I’m wondering why natural materials are used at all on foam patterns? To catch fishermen? Improved Thunder Thighs is moving in the right direction.

    These hoppers are amazing! When I saw this blog title I thought ‘wow, now that’s a specific topic for a blog’. On reading and having a look at some of your patterns, I’m truly impressed. Now, to the tying table to see what I can come up with…
