Tying Recipe
  • Hook: Down Eye, 2x long, straight shank, nymph hook (Dai-Riki #730)
  • Bead: Gold Tungsten Bead
  • Thread: UTC 70 Thread
  • Tail: Coq De Leon Fibers
  • Body: Stripped Peacock Quills and UV Cement
  • Head: Pheasant Tail Fibers for Head with Olive Rabbit Fur
  • Hook: Any standard nymph hook will do (curved or straight shank)
  • Bead: Any bead will work including a glass bead
  • Tail: Pheasant Tail Fibers or Partridge Fibers
  • Body: Stripped Quills of any kind
  • Head: Any dubbing will work, but something that is messy works best with long fibers like rabbit dubbing (antron, ice dub, or SLF whitlock works good too)

Color Variations

This fly is simple in design allowing for a lot of variations.  The easiest way to variate on this pattern is with a thread and dubbing color change.  If you’re looking to imitate darker mayfly nymphs like a hendrickson or march brown, then brown thread and dubbing will do the trick.

I recommend yellow, brown and purple as 3 good color variations as a start.

Rubberlegs Variations

You can also add some legs to the head portion of the fly.  Small rubberlegs, or Krystal flash for legs gives a nice look that I really like.

Euro Variation

The ever-increasing popularity of euro-flies is worth noting.  Nearly every nymph we can tie can be made “euro” simply by using a jig style hook and slotted bead.  This is true for the baetis pattern as well and if you find yourself using this euro/tightlining technique often or getting hung up on the bottom often, a jig-style fly will yield great results.

This simple, yet effective pattern imitates BWO nymphs. BWO are also called Baetis, Blue Wing Olives, and sometimes referred to as olive duns. It’s all the same insect in regards to fly fishing and imitations of those bugs in a fly pattern. This fly is a quick tie, durable and can be tied in a wide range of sizes and colors making it a great staple pattern to have in your box in proper sizes and colors for the insects you want to imitate (for a list on sizes and colors for each insect/species/stages, scroll down and see below).

Check out the pattern below and add a few to your box, you’ll likely come back for more as this fly quickly earns a place in your box.

Though BWO’s are present year round in the river system, early to mid spring and mid to late fall are some of the most important times for Baetis in our river systems.  While you can’t go wrong with this fly, focusing your efforts and keeping them in your box during those times of year will yield the most success.

In addition, BWO’s are rarely bigger than a size #16 hook, so I’d focus most of your sizes on #18 – #22 for this pattern.  It has few materials so it’s easy to tie in small sizes.

When fishing it, get it down deep right on the river bottom and dead drift it for your entire drift.  At the end, stop moving your rod and hold it in place.  The current will drag the nymph upwards in the water column like an emerging baetis and can trigger a lot of strikes.  If you catch fish on the stop/swing like this, try stopping your rod earlier in the drift once the fly is on the bottom of the river.  If it works at the end of the drift, it’s going to work better at the middle of the drift.  Play around with when you do it and as you begin to catch fish, take note and repeat those steps.
