Hatchback Mahongany Dun Fly

About the Hatchback Mahongany Dun Trout Fly

Subtle in hue but deadly in presentation, the Hatchback Mahogany Dun is a refined dry fly pattern crafted to perfectly match the Paraleptophlebia mayfly hatch, commonly known as Mahogany Duns. This American fly pattern is a go-to choice for anglers targeting discerning trout during autumn's prolific hatches.

Characterised by its rich reddish-brown body, gently tapered silhouette, and distinctive split tails, the Hatchback Mahogany Dun also features a unique trailing shuck or “hatchback” to imitate the vulnerable phase of an emerging dun. This realistic trigger makes it irresistible to trout feeding selectively on surface emergers and duns during hatch windows.

Expert Tip:

Mahogany Duns begin to emerge when water temperatures cool, usually autumn through early winter in the western and northeastern United States. Common rivers that see prolific hatches include the Henry's Fork, Delaware River, Madison River, and various freestone streams in the Rockies. Their hatching behaviour is slow, deliberate, and often drawn-out—gives trout plenty of time to inspect their prey, making precise imitation crucial.

Present this fly with a drag-free drift along seams, eddies, and tailouts where trout station during hatches. On bright days, consider pairing it with a Mahogany Spinner or emerger variant as part of a double-dry setup.
