Squirmito- The Original Squiggly Worm Fly. This squiggly worm fly has the tendency to TEAR 'EM UP. Call what you may; squirmito, squirmie wormy, squiggly worm, blah, blah, blah. The only fly that I've used (in 34 years of fly fishing) that fish move 5 to 10 feet on a consistent basis. Keep in mind, this pattern will make you squeamish if you're a dry fly purist. Also, dont leave them in your vehicle or boat sitting in the hot sun (it'll melt).
