Devaux Emergent Fly HL 07-O

Product advantages

The Devaux HL07O emergent flies are designed to imitate the critical moment when the insect leaves its nymphal stage to break the surface, a phase during which trout are particularly selective. Their studied profile, low silhouette and sub-surface balance provide a natural, discreet presentation that triggers takes even on educated fish. Devaux's build quality ensures durability and consistent performance outing after outing.

Technical characteristics

• Emergent design faithfully imitating the sub-surface transition stage.
• Low profile on the water for a natural, unobtrusive silhouette.
• Textured body with high penetration and controlled drift properties.
• Floating and hydrophilic materials judiciously combined for a stable landing.
• Hook with optimized gap, chemically sharpened, for reliable hookups.
• Neat Devaux-quality tying for increased longevity.
• Coloration and calibrated sheens for maximum realism without excessive shine.
• Suitable for fine river fishing and streams with moderate current.

Advantages and strengths

The HL07O emergents stand out for their ability to remain in the surface film, an area where fish actively filter prey. This position creates a convincing visual imprint while minimizing unwanted drag. The material balance allows a controlled buoyancy: the rear anchors slightly below the surface while the front remains visible, increasing read-back for the angler without alarming the fish. The aerodynamic tying facilitates precise landings at distance, even with long leaders, and water penetration is optimized to preserve a free, natural drift. Thanks to the fineness of the tying, the emergent holds up better in light gusts and retains its effectiveness after multiple catches, making it a reliable choice for demanding sessions.

Usage tips

To get the most from the Devaux HL07O, favor a discreet approach and fine tapered leaders, using a floating line dedicated to surface fishing. Apply floatant lightly on the leader up to 20–30 cm from the fly to maintain a natural drift and prevent the end from sinking. Place the imitation upstream of identified rises, then let it drift freely while controlling the line. Alternate pauses and very subtle micro-animations to mimic an insect stuck in the surface film. In low-angle light or clear water, a parachute-style landing with extra cushioning will enhance discreteness. Rinse and dry the fly after use to preserve buoyancy and fiber longevity. If necessary, reactivate buoyancy with a little hydrophobic powder, taking care not to clog the hook to preserve an optimal hookset.

Testimonials

Fly angler for more than fifteen years, I adopted the HL07O for discreet hatch situations at the end of the day. Their hold in the surface film is astonishing and very selective fish take them. Landings remain precise even with a fine tip, and the hook sets cleanly without unnecessary damage. It has become my first choice whenever rises become selective.

FAQ

Is this emergent suitable for fast rivers? Yes, provided you manage the drift carefully. In stronger currents, favor short landings and strict control of the line to avoid drag.

Should it be fully coated with floatant? No. Apply floatant sparingly to the elements meant to stay on the surface and keep the rear slightly submerged to preserve the imprint of a true emergence.

Can it be used in tandem with a light nymph? Yes, in a so-called "duo" rig or "nymph under dry" setup. The HL07O then serves as a reference point while also taking active surface fish.
