Oliver Edwards' Yellow Stonefly is another example of the right way to combine realism and effectiveness into a fly pattern. It features a biot body, dark wing case, and just the right amount of hackle for the legs. Available in size 16.
Oliver Edwards' Black Stonefly is a great choice for imitating small, early season stoneflies like nemouras. Not only does this pattern look like it will crawl right out of your fly box, but it also catches fish too.
The Montana Mini Intruder is the little brother of The Fly Project's Montana Intruder, and measures in at just over an inch long. This fly is tied on a 25 mm articulated shank trailing a #6 Gamakatsu Octopus hook, making it a great choice for swinging and stripping alike. It features brown/tan laser dub head, pearl sparkle braid body, and a bunch of gold, copper, and red flashabou to make this fly sparkle like crazy underwater.
Gee's Supafly Stone is a new salmonfly pattern for 2017, and it seems to have all the right things going on. It features a foam body, light gray wing, and plenty of rubber legs to give it a lot of movement on the water, and the orange dubbing can be easily dulled with a few hits from a brown permanent marker. Available in Size 6.
