Any and all thoughts and patterns welcomed. Every year, after the green/yellow sulphurs, we get Isonychias up in the Catskills. Fun hatch to fish b/c they're typically bigger bugs and the fish key in on them as a nice sized meal.
A google search and a quick check of Youtube gave me all kinds of Iso nymphs, parachutes, comparaduns, but nothing along the lines of a traditional dry. I also searched similarly for Slate Drakes and MahoganyDuns as I know they're also referred to these ways but... nothing useful.
Everyone seems to suggest a size 10 to a 14, gray wings (dyed mallard flank or matched quills, dun hackle points or even EP fibers), a dark dun, or chocolate dun hackle, a gray tail of some sort (CDL?) and then a dubbed body that's primarily a maroon color with blacks, brown, tans and olives mixed in - some suggest an olive or tan ribbing to the body, etc. All this is great, and with these suggestions above I can tie about 634 different variations, not knowing one to be more effective than another. That said, when I look at the mayflies themselves, they look to be dark brown/black & tan in color, and I'm not seeing the ever present/dominant maroon coloring, so...
Does anyone have a pattern they tie for their ISO dries that they swear by???
Thanks in advance, Ed
