Tom's Hexagenia Nymph

by Tom Kilfoil

April 2005

Finished Hex Nymph

This fly is similar to a Hex nymph tied by an Almanor regular, either Milt Jensen or Dr. Del Heacock. I will find out this year and will correct this recipe to acknowledge the correct person. Their pattern is tied with the hook up instead of down as I have tied mine.

While the original used pheasant tail feathers for the tail, I use short fine deer body hair. I like the way the fine deer hair flairs so I use it on all my nymph patterns that have a hare's ear color. This short fine hair is found on the legs of the deer.

I've also use a yellow synthetic yarn instead of the original yellow chenille for the lower body, simply because I have so much of it. For the over-body marabou on the lower body I use a color as close to a light-brown gray as I could find. It is made by Hareline Dubbing and goes by the name Grizzly Marabou, Tan. I've also weighted my flies with medium lead wire (12 turns).

Hex nymphs are perfect to fish with during the early evening before the Hex hatch starts. Some fishermen only use nymphs during the hatch, but my first love is to fish for trout on the surface. Whenever you see me fishing out of a float tube during the hex hatch, you'll almost always find me with two rods. One set up with a floating line and a hex emerger. The other will be a sinking line with either my bead head Hare's Ear Nymph or, now, with this Hexagenia nymph.

  3. Tie in a small clump of short fine deer body hair for tail. Hold it to top of hook as you wrap so it does not spin around hook.
