Hatchback Mahongany Dun Dry Fly

Catalogue No: 4498
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.

Fishing Tips

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. Imitates: Mahogany Dun (Paraleptophlebia spp.) in the dun/emergence stage Best Fishing Times: Late September through November in cooler climates; occasional spring hatches in select regions Water Types: Ideal for Rivers and Streams, particularly slow to moderate flows with clean gravel beds Hook Size: Typically tied on #14–#18 dry fly hooks Hatch Timing: Midday to early afternoon on overcast days offers peak activity Recommended Tippet: 6X for finesse presentations to spooky trout

Request a fly, size or option

We work closely with our fly tyers and can tie most patterns to order: a different hook size, barbless instead of barbed, a tungsten bead instead of a gold head; just ask.

Sending a request is free and you are not committing to buy. Depending on where we are in our tying cycle it can take a month or two for a pattern to arrive, and we may not be able to tie every request (fair usage applies); but if we can, we will.
