Otsego Ant by Alex Cerveniak

Fly Patterns, Step-by-Step Tutorials — By on March 6, 2014 12:02 pm

I forget where I first learned it, but during a Trico hatch, all you need to do to catch the trout that are snubbing your trico pattern is tie on an ant. Over the last 10 years, I’ve found that ants are a trump card that no trout can refuse. This is especially true when you encounter tough to catch fish that are actively feeding on insects that are smaller than a #18. If its mid to late summer and you’ve got fish rising to bugs you can’t see, try an ant and avoid beating your head up against a wall trying to figure out what its really eating.

Ants are also an excellent searching pattern. That is, when there is no hatch, try an ant in all the likely — and unlikely — looking places, and you will almost certainly catch fish all season long.

Why? A big reason is that ants aren’t just around late in the season. For example, last year during the trout opener (late April here in Michigan), I was sitting on the bank and noticed thousands of small brown ants crawling around the grass on the bank. So ants are around all season long in high numbers and they can’t fly away once they fall into the water.

That’s a perfect storm of a combination.

The Otsego Ant (named for the Michigan county where it was developed) is essentially a double Griffith’s Gnat with some red floss in the middle. Many anglers believe that trout see a Griffith’s Gnat as a clump of midges doing the nasty. The Otsego Ant has multiple things going for it. It has red. It looks like not one, but two! midge orgies. And of course, it looks like an ant. And whenever you have a fly that simultaneously looks like multiple prey types, and only takes a few minutes to tie, you are #winning!

Hook: #12 to #22 standard dry fly hook
Thread: Red or Black
Body: Peacock Herl and Red Floss
Hackle: Grizzly
Estimated Tying Time: 3 min.

Step 1


Start your thread above the hook point and create a thread base that goes a few wraps or so behind the barb.

Step 2


Tie in a single grizzly hackle feather

Step 3


Tie in 2 pieces of peackock herl and wrap forward to a point above the hook point. An optional step here is to purposely leave the butt ends too long and use them in a later step instead of tying in two more pieces of peacock herl. This saves one step while tying and isn’t really a big deal unless you’re tying a lot of them in one sitting. You can do the same thing with the hackle, and save two steps.

Step 4


Wrap your hackle forward and tie off.

Step 5


Tie in a piece of red floss

Step 6


Bring your thread forward to the point about two eye widths behind the eye.

Step 7


Wrap the floss forward. Tie in a grizzly hackle feather.

Step 8


Wrap the peacock herl forward.

Step 9


Wrap the hackle forward and whip finish.

    I love the fly.
    A much easier and quicker method of tying this fly is to tie in the middle red thorax last. You get the same fly without the hassle.
    1. Cover hook with thread.
    2. Tie in the hackle
    3. Move your thread back up to the eye.
    4. Tie in the peacock herl and wind it back to the hackle and then forward to the eye and tie it off.
    5. Palmer the peacock herl back to the eye, tie it off the hackle and whip finish. Cut your thread.
    6. Using Red nylon stretch over locking thread (wooley nylon) make three wraps in the middle of the fly and whip finish with four turns.

    Use this same method when tying Royal Wulffs

    Thanks for sharing such a simple, yet great, variation of a couple different patterns. I’m sure a couple will endup in my Grayling box and my “America’s Picky Trout” box.

    Super keen to try this fly. I’ve only been tying for two years and have a lot to learn. Simple ties like this that look great are getting me overly amped for the season to begin.

    Cool fly, I would be wary though of leaving them in a fly box like that and flattening all that hackle down.

    Francis Betters from the AuSable Sportsman’s Shop in Willimington, NY wrote an article on “Ant the Hatch” back in the late 70’s. Beetle the hatch works too!

  6. Hi Paul,

    Thats a nice alternate way to tie this one, great suggestion! I actually tie it slightly different, to save a few steps, but worried that way might feel too complicated for some beginners.

    I met Fran a few times on trips to the NY Ausable when I lived in upstate NY. Great guy and a really innovative tyer in his day.

    Can you elaborate a little more re: step #6 for an old less than expert tyer. I’m trying to picture ..”Red nylon stretch over locking thread”.., and a whip finish in the middle of the fly?

    Great fly. I haven’t had a chance to use it on trout yet, but I can say the bluegills in my private pond go crazy over it. Still early in the season and my ‘gills aren’t all that active yet, but the couple times I’ve thrown this pattern at them they attacked it with a vengeance. I’ve also tied some using orange floss, and also some with green floss with black hackle. All have worked really well. Thanks for sharing this great ppattern with us.
