Blue Flash Damsel and how to fish it like a pro

• Blue Flash Damsel (BFD) nymph is a highly effective fly for stillwater fly fishing, especially during the warmer months when damsel nymphs are active and migrating toward the shallows. It imitates the natural damsel nymph with a touch of flash to trigger aggressive strikes from trout, particularly in clear waters.

• To fish the BFD, use a floating or intermediate line depending on the depth and temperature of the water. A 10- to 12-foot leader with 5X or 6X tippet is ideal. Cast near weed beds, margins, or drop-offs—areas where natural damsels are commonly found. Allow the fly to sink, then retrieve it slowly using a figure-of-eight or short, erratic strips to mimic the swimming action of the real insect.

• Pay close attention during the drop and pause, as takes often happen when the fly is stationary. On warmer days, trout may cruise the shallows, so sight-fishing with the BFD can be extremely productive. When fishing deeper, count down to different depths to locate feeding fish.

• The BFD is a great searching pattern and works well on both stocked and wild trout. Its subtle movement and flash make it a deadly choice when fish are feeding sub-surface but ignoring traditional patterns.
