Isonychia mayflies are among the more important sporadically hatching bugs in the East and Midwest. These insects rarely provide the blanket hatches that make sulfurs and caddisflies so exciting, but Isonychia emerge in light numbers almost every evening for much of the season, long after the “sexier” hatches are over. Although these bugs are generally not as important in the West, there are localized populations.
In this latest how-to video from Tightline Productions, Tim Flagler shows you how to make an elegant, extended-body version of the classic Iso Parachute. Extended bodies look difficult to make, but Tim shows you how–with a needle and a piece of small tubing–you can whip up the tail segment in short order. Then you just finish the parachute as you normally would, and Bob’s your uncle. The result is a fine imitation that’s sure to attract trout.
