Juju Baetis

The Juju Baetis is a modern, highly effective mayfly imitation created by renowned Colorado fly tier Charlie Craven. Designed to match small mayflies and midges, this pattern has earned a reputation for fooling selective trout in a wide range of waters.
Its slim, segmented body—typically crafted from fine tinsel, wire, or synthetic materials—creates a lifelike profile, while a thin, iridescent wing case adds subtle flash that mimics the natural sheen of emerging insects. Tied in sizes 14–24, the Juju Baetis closely matches the tiny mayflies trout often key in on, especially in clear water.
Versatile and adaptable, it performs well in tailwaters, freestone streams, and stillwaters alike. Anglers fish it effectively as part of a nymphing rig or as a dropper, usually with a dead‑drift presentation, though a slight twitch can suggest an emerging insect.
With its realistic silhouette and consistent performance, the Juju Baetis has become a must‑have pattern for targeting picky trout feeding on small aquatic insects.
