You forget how big, how truly enormous, this bug is. Part of it’s the contrast: After a spring spent matching caddisflies, Hendricksons, and sulphurs—and pulling nothing out of your fly box larger than a dainty size 14—the first Hex of the season, battering heavily into the dusk like an overloaded Sikorsky, blows your mind.
This isn’t a mayfly. It’s Godzilla.
