Blue and Black Longtail Fly

About the Blue and Black Longtail Salmon Atlantic Fly

The Blue & Black Longtail on a Treble Hook is a bold, modern salmon fly built around one of the most time-proven colour combinations in Atlantic salmon fishing. Blue and black has long been regarded as a dependable pairing across the UK, Ireland and Scandinavia, particularly in clear or lightly peated water where contrast and silhouette are critical.

This longtail variation enhances that traditional formula with extended rear fibres that create exceptional movement and flow when fished on the swing.

The fly features a slim, lightly ribbed body with subtle flash for added attraction. A vibrant blue throat and underwing form a strong visual trigger point, while the sleek black wing is interwoven with fine strands of flash that shimmer and pulse in the current. The elongated longtail produces continuous, lifelike motion, giving the fly added presence in medium to fast water.

Mounted on a strong treble hook, this pattern offers excellent hooking security and a confident fishing profile, making it well suited to classic salmon pools and steady glides.

Fishing Tips:

Blue and black patterns have earned their place in salmon fly boxes for decades due to their strong silhouette and consistent effectiveness. The longtail design builds on that legacy by increasing animation without adding unnecessary bulk.
