The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

earlier in the spring, this site helped me create a very effective emerger fly for the green drake hatch. the wings were made of a mixture of yellow and olive antron yarn to try to duplicate the color Jason caught in the photographs.

now the idea for a wet fly for the same hatch occurs to me. are there any birds that have natural olive and/or yellow feathers to use as wet-fly hackle? is there any other substance with a slight sheen that could act as wet fly hackle?

Casey-

Good grief. Where did you scrounge up that word?

Anyway, if you can't find natural feathers in that color, what about using dyed feathers? One thought which came to mind was the wet hackle used on an Olive Willy.

the hackle on Olive Willy is perfect. thank you!

Good grief. Where did you scrounge up that word?


we had no television when i was young, but we did have a complete set of Kipling and a mother who loved to read out loud. once you get your infant tongue around "a man of infinite resource and sagacity" there is no turning back. my other favorite is antediluvian, as in "I must get over my antediluvian aversion to dyed feathers."

hey, at least lovely old long words aren't banned around here...;-)

Hi Casey,
A soft-hackle emerger, in my opinion, would work well for the Green Drake. I tied one up a few years back, but it can always stand some improvement. Here's a where you can find the recipe.

Mark,
what a nifty pattern! thanks for the recipe, and for the idea for a hackle made of "real" feathers the right color. my daughter works at A.C.Moore, a mega craft store, so i'll take a look there as well for something sort-of-brownish-yellowish with spots. once you get into the idea that color really matters, life gets very complicated, doesn't it!
