Henderson's Master Baetis – Gray

Henderson’s Master Baetis – Gray is a deadly midge and mayfly emerger pattern that imitates one of the most vulnerable and targeted stages in a trout’s diet: the moment of emergence. Tied with a slim gray body, realistic segmentation, and a buoyant foam wing, this pattern hovers in the surface film or just below it, perfectly mimicking a struggling baetis or mayfly caught mid-transition. Its natural gray tone blends in during selective feeding scenarios, making it ideal for picky fish on clear water tailwaters or spring creeks.

Crafted for maximum performance in subtle hatches and pressured conditions, the foam wing helps the fly suspend slightly off the bottom or in the film, depending on rigging. It’s equally effective as a shallow emerger fished behind a dry or as the trailing fly in a two-nymph rig. The slim profile and lifelike movement make it an indispensable option during blue-winged olive hatches and midge emergences.

To fish Henderson’s Master Baetis – Gray effectively, present it in a dead drift with light tippet and a drag-free presentation. Use it in flat water or slow seams where fish are rising subtly to emergers. It pairs well under a parachute dry or in a soft hackle emerger rig when fish are feeding between depths.
