A simple pattern with a bit of extra flash that makes all the difference. In fact, the flashback imitates gases that fill up within the mayfly nymph’s case, which helps it float to the surface. We love to fish this nymph under a dense foam pattern. Or, give this a go under a small foam indicator.
A versatile nymph pattern excellent for prospecting for trout.
Sure, this is a bread and butter, no frills fly, but Fly Crate's tie on it is top notch and noticeably more durable than cheaper alternatives.
When there is a little but of color in the water, or when I can't figure out what fish are hitting, I tie a this with a tungsten Rainbow Warrior as a two fly rig and have done very well prospecting.
