Ken Morrish's Fluttering Stone

This series took a lot of time and observation to develop. Maybe the most significant observation and correction was that the vast majority of adult stonefly patterns have broad, bulky or heavily hackled heads, wherein reality stoneflies have very slender head profiles. These are very complicated flies to tie but when done right, they perform exceedingly well and are worth the effort.

These patterns have highly accurate profiles, great specific density, realistic jointed rubber legs and are darker and more realistically colored than most commercial patterns. They also have realistic segmented bodies and high-vis locator patches. Just put it where it needs to be and maybe wiggle it once or twice.
