Isonychia Nymph

$4.50

Available Sizes#10 - #14
Color Variations
Dark MahoganyBrown/White LegsMaroon

Isonychia nymphs are the marathon runners of the mayfly world -- fast, sleek, and perpetually in motion. They swim through the current column like tiny competitive athletes, and trout intercept them with the precision of a pickpocket on a crowded subway. This imitation captures the dark body and pale legs that trout look for, because even predators have standards when the buffet is this specific.
