There is a chance of running into the Isonychias from now
until Fall as they have three broods that hatch throughout
Zug Bug nymph, but with an insect as important as this
one, it sometimes pays to have a more exact imitation.
Our new pattern includes Hare'e Ice dub in Harder's
Bloody black color for the abdomen and peacock ice dub
for the thorax. We can create the illusion of an extra long
abdomen with a 3X long hook. The color and shape are
correct and this one should produce well.
Hook:               Dai-Riki 710 #12
Thread:            Black Danville 6/0
Tails:                Peacock Herl
Overback:        Dk. Turkey Tail
Abdomen:        Hare'e Ice Dub Herter's Bloody Black
Rib:                   Dk. Brown Uni flex
White Stripe:    White Uni Stretch
Thorax:              Peacock Ice Dub
Legs: English   Grouse feather
Wingcase: Dk. Turkey Tail.

1. Put a slight upward bend in the front portion
of the hook and tie in three peacock herls.
2. Wrap lead wire on the rear portion of the
hook and flatten with pliers.
3. Tie in white Uni Stretch for the white stripe.
4. Tie in Turkey tail and ribbing on top of hook.
5. Make a dubbing loop and insert dubbing for
the addomen.
6. Wind dubbing on rear 3/4 of the shank.
7. Pull overback over the top followed by white
stripe. You may have to twist the uni stretch to
get the proper size stripe.
8. Wind Uni Flex rib stretching it as you go and
winding with a little less pressure as you get
near the front. This gives you a wider rib on
the front portion of the abdomen.
9. Pull White stripe and wingcase to the rear
and wind towards the rear to form the
10. Prepare feather for the legs by notching
out the middle of the tip as shown.
11. Tie in feather in front of thorax as shown.
Legs should fold down around the sides.
12. Fold wingcase over followed by white stripe
and secure to complete the Isonychia nymph.
I've read where the white stripe isn't present on later broods
throughout the year, but haven't seen this. The stripe may or may
not be important. I've also seen enough emerging from the water
that I don't believe that they all emerge by crawling out on rocks
or sticks. On streams where they do, you will surely see the
shucks on the rocks.
The Isonychia likes overcast days and you will frequently see the
BWO hatching along with it.
