A timeless, fishy wet fly for light mayfly activity. The Light Cahill Wet suggests an emerging or drowned pale mayfly; its soft hackle breathes on the swing and the light, creamy body shows up naturally in clear water during evening hatches.
-
When it excels: Late spring through summer, especially evenings during Light Cahill/BWO-style hatches; riffle tails, seams, and gentle glides
-
Why it works: Pale body and soft hackle create a convincing, low-key mayfly silhouette that pulses on the swing and lift
-
Pack size: 3 flies
-
Targets: Trout (rainbow, brown, brook)
-
Ready to fish: Durable wraps and clean proportions for repeatable, natural drifts
How to fish it
Cast down-and-across, mend for a slow swing through the seam, then add a gentle lift at the hang-down to trigger eats. In slicks, grease the leader to keep the fly just under the film, or fish it as the top fly above a small nymph. Use 4–5X and keep swings short and controlled.
Care
Rinse after use and air-dry before boxing to prevent hook corrosion.
