Podobed's Spite Stone
This fly is a very new evolution of one of my favorite early european nymphing flies- NJ Euro Guru and fly fishing author Aaron Jasper's Drone Stone. 

His fly was a 2 tone woven stonefly, and I'm updating it using some newer materials to make it faster and probably more durable as well. 

This is a great attractor pattern, as well as a good fly to use for the Golden Stonefly (Hesperoperla pacifica) or for the Yellow Salley (Isoperla fulva) when scaled down.
