Ira Lindgren is another pioneer of fly fishing and tying. He lived in an era where flies were easy to tie and simplistic. Lindgren lived near the Kings River in Dinuba, California. where he snorkeled often to observed trout and the way they feed.
Ira was responsible for devising quite a few patterns- especially nymphs. Most of his nymphs contained peacock in one fashion or another. Many of his patterns still have quite the following in the Sierras. However, little is known about his dry fly patterns. From the research I done it appears peccary was a staple of his dries and much of his stock was shared with Doug Prince (Pig Nymph) and Wayne "Buz" Buszek (Buz's Fly and Tackle, Visalia, California).
Perhaps his best known pattern is the Lindgren's Olive. However, the Lindgren's Peacock is super simple to tie and highly effective to this day. This pattern comes with a strong recommendation from me to those just beginning in fly tying/fishing. It is a pattern that I use often in the waters of Northern California.
(1) The pattern should be weighted.
(2) Only use peacock herl from near the eye. Not only is this the best area for color and thickness, but gives the pattern a lot of "juicy" bulkiness.
(3) Once the hackle is wrapped trim a few fibers from the top and bottom. This will give the appearance of legs alongside the body.
Hook: Standard nymph hook. Lindgren would have tied this pattern on a Mustad 7957BX or 3906B, sizes 8 to 14.
