San Juan Worm, Red
Some aquatic worms are reddish. We have never seen any worms as bright as these flies, but don't let that fool you. There have been lots of trout caught on this pattern.
San Juan Worm, Worm Brown
Many aquatic worms are tan to brown in color. This pattern seems to work best in streams and lake that have very clear water.
San Juan Worm, Hot Pink
We spent a lot of time screening the Deschutes River, looking at the aquatic invertebrates that live there. The majority of worms that live in the substrate are pinkish. The first time we fished this pattern during spring runoff, the trout gave it two thumbs up.
San Juan Worm, Shell Pink
Some worms are very light colored. It doesn't seem to have anything to do with the color of the substrate they are living in. Lighter colored worms are often better when fishing in clear water.
