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.
Please note all of our fishing flies are barbless unless otherwise stated.

Why Choose the Grannom Dry Fly?
Spring Hatch Specialist
Designed to imitate the Grannom caddis (sedge) during peak emergence periods.
Natural Profile
The tented wing shape accurately reflects the adult sedge resting on the surface.
Selective Feeding Solution
Ideal when trout are keyed in on early season caddis.
How To Dress The Grannom Dry Fly
Apply Floatant To Wing & Hackle
Lightly treat the wing and hackle before fishing to maintain buoyancy.
Keep The Body Lightly Treated
Avoid excessive floatant on the body so the fly sits naturally in the surface film.
Refresh As Needed
If the fly becomes damp, use amadou or desiccant powder to restore flotation before recasting.
How To Fish the Grannom Dry Fly
Upstream Dead Drift
Cast upstream and allow the fly to drift naturally with minimal drag. Accuracy is key when trout are rising steadily during a hatch.
Target Hatch Zones
Focus on slower glides, pool tails and sheltered runs where adult sedges collect on the surface.
Evening Sedge Activity
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)
