As March rolls on, here are three stone fly nymphs that I've been fishing. The fly on the left is a cross between a black zebra midge and a soft hackle. I've tied this one in size 18 and 20. This simple fly uses black thread, an extra small silver wire rib, black peacock ice dub, a gun metal tungsten bead, and a few turns of dark hen hackle. I've caught hold-over browns and rainbows as well as wild browns and brook trout over the last couple months on this fly, It also fishes well as a dropper behind your favorite winter dry fly.
I also tie this one in size #16 (to the left) for the more typical size of the early stone flies. The materials are the same and instead of the extra small wire, I use small silver wire on a #16 competition nymph hook (lately I've been using the Hends BL 254 hooks).
I had a few pink metallic tungsten beads kicking around so I tied this last one just for fun. Who knows if I will ever fish it, but I like the look of it.
