One of the early hatches in MI is the Slate Wing Mahogany. The dry fly versions of this are, confusingly, called Mahogany Dun and Blue Quill - Two completely different colors. (1) Does anyone know why ? (2) Does anyone know the fly patternrecipename for this fly in Mi - I want to tie it ?
Thanks !! Brian314

Welcome to another Michigander on the forum! You're up there in NW Kent Co, apparently...and a short trip to the Rogue or Muskegon.

Blue Quill refers to wing color (a dark grey/dun) and Little Mahogany (reddish, dark brown) refers to body coloration. Both are local names for Paraleptophebia spp. and a good earlier hatch for your local waters...Google these names and a bunch of patterns will turn up, and past experience shows sz 16 nymph and dry flies work best for me.

The Slate Wing Mahogany is another fly altogether- Isonychia spp. (sz's 10-12 with some smaller exceptions later in the season) which should appear in late June through August dependent on temps and other variables. This is a heavy and fairly dependable hatch on the Muskegon.

(asking forgiveness if you already know the above info, I'm often too willing to share stuff).

See you on the stream next spring...I'll be the whiskered old fart flogging the water with a trout spey-rod,

tight lines!

My mistake in noting the Slate Wing Mahogany as an Iso, it IS another name for Paraleptophlebia spp.(thanks to the insect ID section of this forum and Dr Jason)

Isonychia spp. are known as a Slate Drakes or Mahogany Drakes, per Ann Miller's excellent 'Hatch Guide for Upper Midwest Streams', another valuable resource for tyers and fly-fishers alike.
