Product Description

What fly fisher doesn't enjoy mayflies and microbrews?!  Join Aquatic Biologist and Trout Medium Peter Stitcher for a look beneath the surface of the water and into the mind of a trout.  In this 2 1/2 hour class, Peter will delve into the sciences of trout habitat selection, trout feeding behavior, entomology, and stream dynamics – breaking them down into easily applicable skills for the fly angler to experience greater success on the water.

Topics to be covered include: Understanding trout habitat – Where do trout hold and why; What do trout see & how trout vision pertains to fly selection; Streamside Entomology 101 – Identifying Invertebrates at a Glance; Matching the Hatch – tying on the patterns the fish want to eat.

Participants will receive a handout illustrating topics covered in the class, and a pack of 15 flies as a companion to the entomology portion of the class.

Take a minute to watch this short story by Denver Channel 9 News to see what to expect from this class!


The November class will be held from 6:00-8:30pm at Jake's Brew Bar:  2540 W. Main St. Littleton, CO 80120

  1. Excellent class

    Posted by Dave Karnell on 20th Nov 2017

    This was a well organized, interesting and informative class. It was without a doubt, the best fly fishing class I have ever attended. It was well worth the time and money and the location added to the fun. I highly recommend this class. Thanks for sharing your knowledge Peter.

  2. Learned a lot

    Posted by Joey on 23rd Oct 2017

    This class gives you the insight behind how and why trout will eat your flies. Definitely worth the time and money. Makes me want to fish so much more

  3. Great Class

    Posted by Mike on 18th Oct 2017

    I have been fishing all my life and fly fishing for 15 years and I still learned a lot of new stuff at this class. Well worth the time and clearly worth the minimal cost to gain more insight to better enjoy this sport.

  4. Helped me catch more fish! - 26 year vet

    Posted by Peter Martin on 13th Aug 2017

    I learned how to fly fish at 10 and have been doing it for fun over the years with inconsistent results. However, this past year I've dedicated my efforts to take my fishing to the next level and have been reaping the rewards. I attended Pete's class at the suggestion of a friend who I've been teaching how to fly fish. I came in not expecting much but left pleasantly surprised and eager to hit the water! This class lays a foundation to understand the natural world you enter when stepping into a trout stream: river dynamics, trout biology & associated behavior, and insect biology. As an experienced angler, Pete first explains the science behind a concept, and then tells you how you can "exploit" it to catch fish; he also reveals many useful, local tidbits for the Colo area. This class not only helped explain many things I've witnessed on the river, but also revealed some really cool new concepts. Pete provides a paper packet of his presentation slides, which I photo'd & saved on the cloud & my phone for quick reference. He includes a small selection of flies with a breakdown of each; I actually took them to the Williams Fork the next weekend & used the parachute caddis to land a beautiful 15" rainbow! Pete covers a TON of info during the session, so I'd suggest taking notes as he speaks. He brings some tools for sale; I bought a net seine for sampling insects on the water. Most importantly [and better than a book] Pete is available to ask Qs in person, at the class or later via info on his business card. This class is a great way to spend an evening; I left feeling eager to utilize my new knowledge on the water & refreshed towards a hobby that had grown a little stale in my eyes. A lot of fly fishing these days is all about the latest gear or referring to it as an "industry". To me, fly fishing is about connecting with the fish: understanding & appreciating their world. As a biologist/angler, Pete gives you the tools to make this happen.

  5. Excellent value for my time and money!

    Posted by Travis on 30th May 2017

    Peter is knowledgable and very generous with his knowledge. If you want to "up" your bug game, this is the class. The course is packed with information, but it is still approachable with Peter's instruction. I will be more confident in my fly selection. Luckily, I am applying my new learning later today. Thanks Peter.

  6. Great class!

    Posted by Josh Kalina on 27th Apr 2017

    Class was great! Learned skills that I will definitely use! Peter is an awesome resource!

  7. Money Well Spent - Fantastic Class

    Posted by Phillip Beckett on 2nd Mar 2017

    This class was a huge benefit to me as I am just starting to learn about fly fishing. I truly enjoyed this class and feel like I came away with more knowledge than I expected. The fly box he gives you illustrating the various stages of fly life cycles is a really awesome teaching tool. Peter is an open book for any questions during and after the course which is great.

  8. Fly Fishing Science - and More!

    Posted by Mark Swalley on 2nd Mar 2017

    I have been a fly fisher for several decades. I feel like I have always known how to read the water and to adjust the depth of my nymphs, but listening to Peter help to reinforce some ideas, and I gained several new insights, including the organization of my fly box. Can't wait now to get back in the river and put it to use!

  9. So glad I attended this class

    Posted by Chad Smith on 1st Mar 2017

    As a fairly new fly fisherman, normally fishing fly and bubble on lakes. I was very unprepared to make the switch to fly fishing. This class has opened my eyes; now when I look at a river I will know where the fish are, and where I should be dropping my flies. Speaking of flies. Do you know how to match the hatch? Take this class. You won't regret it.

  10. Outstanding class!

    Posted by Steve Hanson on 25th Jan 2017

    Very well done. Good information on how to read the waters and how to determine what the trout are feeding on. Best source of information for fishing for trout that I've seen since I tried to learn how to fly fish ac couple years ago. Can't wait to use this fishing on the rivers.
