There are the simpler Stonefly patterns: Bitch Creek, Montana Stone, Brooks’ Stone (look up on Google Images). Some 20+ years ago the Kaufmann Bro’s of Tigard, Oregon presented the Kaufmann Stonefly. It is still here, and more often than not, it now has rubber legs. The original blended dark dubs can be substituted with tans and golds for Golden Stones, Brown Stones (large and small). Always heavily weighted to dredge the depths (remember most Stoneflies crawl toward shore to emerge onto land at the pre-emerge phase at some point). Research the time of Spring-Summer for various Stonefly emergences.
