HOOK: Dai Riki 270 size 10-14 THREAD: Yellow BODY: Golden yellow/yellow-brown sparkle dubbing WING: Golden yellow CDC UNDERWING: Golden Krystal Flash OVERWING: Shimaizaki Fly Wing, or other synthetic winging material. LEGS: Golden yellow CDC

Uses

Imitates adult Isoperla stoneflies (little yellow stoneflies). Little yellow stoneflies can be important on larger streams during the more publicized glamour hatches, so make sure you pack a half-dozen or so everywhere you fish during early and mid-summer.

How to Fish

Use standard dry fly presentations.

 
Do NOT dress the fly with floatant! When the fly no longer floats well, put it in a small container of powdered descicant and shake it up. This removes the moisture, and you're ready to cast again.

This pattern is not difficult or tedious to tie, and you can fill your box in a short time.
