Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).
fluffy...for a wooley bugger or other fly with a marabou tail, two things will make the tail fluffier: more marabou, and tying it carefully at one place. be sure not to allow the thread to wander around the area because that will bind down all those fibers you want to fluff up.
remember, too, that once the fly is wet and you take it out of the water, it's going to look pretty pathetic--all mushed flat. it took my Best Fishing Buddy a while to realize that what he thought were rabbit-poop shaped wet flies actually fluffed out underwater and looked alive. same with marabou tails.

I agree with Casey on the general advice. It would really be helpful if you say which flies you're tying. The best way to make them "fluffy" can be different for different types of flies.
