Benefits and strengths

The Devaux Terrestrial Flies JBT 01 stand out for their exceptional realism and high effectiveness. Their shape and color faithfully mimic the main terrestrial insects that are a key part of fish diets, particularly trout and grayling. Their remarkable buoyancy ensures a natural presentation even in strong currents. Their versatility, resulting from a careful selection of materials and precise artisanal tying, allows them to be used both for river fishing and on lakes. This technical choice ensures consistent performance regardless of season or fish activity level, offering a higher success rate.

Usage tips and recommended rigs

To get the most out of these artificial flies, it is recommended to opt for a thin and discreet leader to preserve the lure's natural presentation. A dead drift rig is particularly effective, as it allows the fly to behave like a real prey floating on the surface. Use them on sunny or windy days when many terrestrial insects fall into the water, or as an alternative when fish refuse classic hatches. A controlled strip, combined with a stealthy approach, will put all the odds in your favor.
