Devaux Terrestrial Fly B513C

Product strengths

The Devaux Terrestrial Flies B513C are designed to provide a convincing imitation of terrestrial insects that fish naturally find on the water surface. Their carefully studied profile, balanced silhouette and quality materials ensure excellent presentation and durable performance, even after multiple takes. Thanks to their ability to trigger opportunistic strikes, they are a reliable choice throughout the season.

Technical features

• Precise terrestrial imitation design for delicate and technical dry-fly fishing.
• High-quality, chemically sharpened hook for immediate penetration.
• Selected materials for long-lasting buoyancy and a stable silhouette.
• Refined finishing for a natural presentation and controlled visibility.
• Robust tying to withstand repeated sets and strong fighting fish.

Benefits and highlights

Terrestrial flies are essential imitations when fish target prey falling from the bank, such as beetles, ants or small land insects. The B513C focuses on understated tying and accurate proportions to maximize the fish's confidence at the moment of suction. Its buoyancy, supported by water-repellent materials, allows fishing the margins, calm seams and slicks while keeping the fly well visible without overloading the drift. This approach improves detection of subtle takes while maintaining a delicate laydown that does not spook wary fish. The realistic imitation, combined with consistent floatation, provides a decisive advantage during low-water periods or under heavy fishing pressure. In variable conditions, the versatility of the B513C makes rapid adaptation easy, whether fishing upstream, controlled drifts or prospecting spots under overhangs.

Usage tips

To get the most from the Devaux Terrestrial Flies B513C, favor a fine, long and discreet tippet to optimize the drift. A tapered leader with a tip suited to clear water promotes a natural laydown and reduces glare. Approaches from a distance, discreet wading or from the bank are recommended to avoid disturbing the margins. On slicks, present upstream with a free drift, correcting the line to prevent drag. In faster seams, slightly control the line to stabilize the fly without stifling the drift. When activity slows, alternate minimalist animations with micro-tugs to simulate a distressed insect, which often triggers reflex strikes. After each catch, dry the fly with a piece of fur or a hydrophobic product to maintain its buoyancy and preserve its original silhouette. Store it dry between sessions to extend its lifespan and protect the tying quality.

Testimonials

“Tested throughout the recent season, the B513C proved extremely consistent on small and medium rivers. Drifts along the margins, under the canopy, produced the best fish. The discreet laydown and the ability to stay afloat after several sets convinced me. Late afternoon, with a simple line control, I got clean rises from educated trout. It's a go-to pattern to remember when hatches calm down and fish turn to prey falling from the bank.”

FAQ

Does the B513C work in still water and faster currents?
Yes, its balanced rig ensures good stability in moderate current and a discreet laydown on slicks, provided tippet length and drift are adjusted.

Is special maintenance required to preserve buoyancy?
Regular drying with a patch of fur and a light hydrophobic treatment are enough to maintain long-lasting buoyancy throughout the session.

Is it a good choice during periods of low insect activity?
Yes, the terrestrial imitation provokes opportunistic strikes when hatches are scarce, especially when fishing margins and under overhangs.
