The Isonychia soft hackle is an excellent pattern to fish during an Iso hatch, and for me it’s a pattern I will swing, even through rising fish.
During an Iso hatch the emerging insects move as fast as they can towards the surface.. And that’s where this fly comes in.
Isonychia soft hackle
Hook: standard wet fly hook
Tailing and hackle: Whiting’s Hebert Miner Wet Fly Hackle in Wild type Brown.
Dubbing: A mix of red and brown SLF squirrel dubbing as well as guard hairs taken off of a squirrel skin.
Stripe: doubled over white thread or one strand of thicker thread or embroidery floss
Ribbing: Gold Wire
Step one Tie in your tailing
(If you are following along from our PHWFF group in New City, or just Need a little extra help; click on the hyperlinks and it will take you to an instructional on certain techniques)
Now you want to tie in your white thread at the base of the tail
Now tie in your gold wire at the base of the tail on the side of the white thread.
Mixing the dubbing:
Next up is dubbing and SLF squirrel has got to be my favorite. What I do for this is I take a mixture of red and dark brown and I mix them together. Then I snip a patch of guard hairs off of a full squirrel skin and mix them in.
This will give you a good reddish-brown mix but be sure to adjust this based on the Isonychias in your area because colors always vary.
Dubbing the body:
Using your dubbing, create a dubbing noodle.
And dub your hook shank, stopping about 1/4 of the way behind the eye, ensuring that you leave enough room to tie in the hackle.
Once you have dubbed the body it’s now time to create the visible stripe that goes along an Isonychias natural nymph body and rib it with wire . You will do this by Bringing the white thread forward, then using your finger nail it to hold it down as you tie it in with a wrap.
Creating the hackle collar
Now its time to select, prepare and tie in your hackle.
Once your hackle is wrapped, you can whip finish and your fly is complete!
Thats it! I hope this pattern brings you luck! I like to fish this one on an upstream cast and then a lift at the end of your swing.
If they are taking them on top as well, feel free to add some dry fly floatent to these and fish them right in the film. It has caught many trout for me that way.
