Callibaetis – Thorax

Short, weird, and oddly effective — meet the Callibaetis – Thorax: a grey take on the classic Mayfly dry fly that insists on standing tall (literally). If your fly box needs a personality upgrade and your catch list needs a boost, this is your new go-to.

Who it's for: anglers who care about subtle realism, selective trout, and making every cast count. Perfect for dry-fly purists and anyone who likes their flies to mimic nature with a wink. AXG Life — Life, Adventure-Ready.

Key Features & Design

• Pattern: Callibaetis – Thorax, a grey modification of the Mayfly Dry Fly.
• Wing style: Single wing oriented upward (instead of the typical side wings) for a distinctive silhouette on the water.
• Sizes: Available in sizes #14 through #20 to match hatch and trout mood swings.
• Finish: Natural, muted grey tones to mimic real Callibaetis and avoid spooky trout warnings.

Performance & Benefits

This fly doesn’t just sit pretty — it works. The upward single wing presents a slim, realistic profile that trout recognize and won’t ignore. That upright posture improves visibility for you and reduces drag, helping it ride higher in the film. Translation: better float, clearer silhouette, more confident strikes.

Whether you’re matching a calm hatch or sneaking a late-afternoon dry-dropper, the Callibaetis – Thorax turns stuck weekends into hero stories. Built for patient stalks, midnight reflex casts, and the questionably brilliant moments that make fishing fun.

Pro tip: Choose a size #14 for bouyant visibility on breezy water, and go down to #20 when the trout are reading tiny fonts that day.

Ready for the River?

Toss the Callibaetis – Thorax in your fly box and make your next drift look like a nature documentary with an attitude. Add it to your kit and let the trout decide who's cleverer — you or the fly.
