This has got to be one of the top 5 easiest fly patterns of all time. It is super quick, durable, and catches it’s fair share of fish. A true “Guide Fly”.
Caddis larva are available to trout year round. The Green Rock Worm caddis imitation has very few steps, and is a very easy fly pattern to tie. It can be used as a searching nymph, or to match the available food types in a given stream. It is bright and catches the attention of fish, so it can be used effectively as a lead fly in a tandem nymph rig to attract the fish that often will then take the small trailing realistic pattern. However, don’t let that fool you. This pattern represents free-living caddis and takes picky trout on very tough rivers. Here in Utah, Provo River fly fishing guides often tie up and fish this pattern because it is so easy and so effective.
The Lower Provo can be a very tough fishery. As the summer rolls along the fish become more and more educated and the pickier they seem to become. Often times guides switch to drab natural nymphs, and that regularly gets the job done. However, despite being bright and flashy, quite often I have found this green rock worm fly pattern to be the fly of choice. As trout catch onto fishermen and their fly patterns, I have found that my success rate goes up when fishing the smaller sizes 18-20. Go figure!

After a couple of years of tying, I was drawn to learn how to weave. It seemed easy enough…..until I tried! It took me some time to learn, but now my box is full of these bugs! They are a durable fly that catch fish! They are built like a rock, so they sink fast. The other reason I like these bugs is that there are an endless amount of variations to this fly. It can be built like a caddis, stonefly, cranefly, or whatever else you can think of. Please see the pics of some of our favorites variations!
A quick story on this fly, I had been tying this fly and trying it out for a year or so before I finally decided to really give the fly a try on my local river. The day ended up with two 20″+ browns making their way into my net (along with many other fish!). I have caught a lot of fish on this river, but nothing over 20″. It was a memorable day, and I often start the day off with a version of this fly!! (see video below to see story and fish caught with woven nymphs!!)
Here is another simple, yet effective pattern. This is a peeking caddis tungsten nymph. I started fishing this pattern just over a year ago and it has been a great producer. The more I have been fishing with jig hook nymphs, the more I have been liking them. Since they ride hook point up, you can add more weight without the worry of snagging on the bottom. Without the worry of snagging the bottom, you can really go deep with these types of nymphs while fishing the European nymphing techniques.
I originally tied this pattern up to help me imitate some mothers day caddis hatches. This fly really works in the springtime and is a go to pattern that time of year, but I have also been using this fly as a general attractor nymph. I have since bought some pearl core braid in other bright colors that include orange and pink, and plan to fish these colors in the upcoming winter.
Get out and fish these flies! TIGHT LINES!
