Originally designed as a spent caddis pattern, we took "caddis" off the end of the name, as this sparse pattern has proven absolutely deadly at mimicking nearly every insect category, from caddis to mayflies to small stones to terrestrials. This fly works great as a "stand out" in blizzard hatches. Something magic here...
