Video: How to Tie Barr’s Emerger BWO

The world’s most famous fly-tying dentist, John Barr, designed his Barr’s Emerger series in 1975, after spending a day fishing a pale morning dun hatch on Nelson’s Spring Creek in Montana’s Paradise Valley. Writing in High Country Angler, Barr described how he came up with the concept:

There were fish rising everywhere, but none were taking the duns. They were taking little yellow specks. At the time I had never heard of emergers, and only carried dun imitations. I finally tied on a nymph and caught a male rainbow with a big mouth that I could easily look down inside of. On the tongue rakers at the base of the tongue were dozens of partially emerged PMD, just a small part of their body protruding from the shuck. In my motel room that night, the Barr’s Emerger was created, and the basic pattern has not changed to this day. The first patterns were on a dry fly hook and fished in the film. I then added a wet version to be fished as a subsurface pattern. In subsequent years I added a bead and flashback version.

In this great video from Tightline Productions, Tim Flagler walks you through the steps to tie this useful pattern on a tiny, size 22 hook. As usual, the way Tim prepares and ties on the materials makes even such a diminutive pattern seem pretty easy to tie. Make sure watch Tim’s videos in full 4K resolution. You’ve never seen fly tying look so good.

  1. I just viewed your video about the Dog Nest, and I enjoyed it very much. Your products are of very good quality. Bravo for considering the health of dogs. I think that it’s wonderful to have a loving animal companion, especially as we grow older. However, we are not all able to buy such expensive items if we are retired and on a fixed income. Keep up the good work. Sincerely, Linda.

  2. I own 2 of the tempurpedic orvis dog beds ( I treasure now!) I also have 3 other dogs beds ( memory foam bolster ) I trust Orvis for all my 4 dogs needs!
    I have one dog ( a young golden retriever, Scooter , that has to have the large fleece Orvis bone inside his ruffland crate as a head rest ! He is super particular & recently his Westie sister tore a hole in his bone- I had to run to my local Orvis store in Birmingham AL ( where they so kindly had one on hold for me !) Scooter could sleep peacefully again.
    I love this company’s values more than any company in the US !
    Wheh I go to Oxford, UK I always visit a local Orvis in the nearby Cotswolds ! To bring my dogs a surprise home!
