The Grannom Dry Fly is a dedicated sedge imitation designed to match the early season grannom hatch, one of the most significant spring events on many rivers. Typically appearing in March and April, grannom sedges can hatch in large numbers, often triggering intense and focused surface feeding from trout.
This pattern is tied to represent the adult sedge as it sits on the water after emerging. Featuring a slim olive or dark body and a tent style wing profile, it closely mirrors the natural insect’s silhouette. The fly sits lightly on the surface, making it ideal for presenting to trout rising confidently during a hatch.
Although primarily associated with spring, the Grannom Dry Fly can also suggest other small sedges and caddis species throughout the season. Its understated, natural appearance makes it especially effective on clear rivers where trout inspect surface food carefully.

Designed to imitate the Grannom caddis (sedge) during peak emergence periods.
The tented wing shape accurately reflects the adult sedge resting on the surface.
Ideal when trout are keyed in on early season caddis.
Lightly treat the wing and hackle before fishing to maintain buoyancy.
Avoid excessive floatant on the body so the fly sits naturally in the surface film.
If the fly becomes damp, use amadou or desiccant powder to restore flotation before recasting.
Cast upstream and allow the fly to drift naturally with minimal drag. Accuracy is key when trout are rising steadily during a hatch.
Focus on slower glides, pool tails and sheltered runs where adult sedges collect on the surface.
During late day hatches, present the fly near overhanging vegetation and marginal areas where adult sedge often return to lay eggs.
(Sorry to state the obvious: caddis and sedge refer to the same insect (order Trichoptera), with ‘sedge’ being a common term used by anglers, particularly in the UK, while ‘caddis’ is more common in America)
