Hex Mayflies
Hexagenia limbata

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.

Neoleptophlebia Mayfly Nymph Neoleptophlebia Mayfly Nymph

Dorsal view of a Neoleptophlebia (Leptophlebiidae) Mayfly Nymph from the Yakima River in Washington

Some characteristics from the microscope images for the tentative species id: The postero-lateral projections are found only on segment 9, not segment 8. Based on the key in Jacobus et al. (2014), it appears to key to Neoleptophlebia adoptiva or Neoleptophlebia heteronea, same as this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.

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.

It's the time of the year when big browns and rainbows travel upstream to spawn! You can have great fun by traveling to a local small, clear stream with native trout and catch many small to lunker sized fish.

Gear: Orvis Super Strong 6X tippet, 4 to 6 weight line, 7 to 8 foot rods, good disk drag reel
Flies: Glo-Bugs of Many colors, 12-16, Sucker spawn and Crystal Meth Egg Sacks 12-14, Bead-head nymphs 14-16, other flies of your choice
Fishing Techniques: Find a good run or pool in your small stream, wear green, brown or even camo clothing, stay back a little, crouch, don't move much and try to keep fly-line off the water. These fish spook very easily, so be careful!

Many people wouldn't think of this on the time of the year, but just remember, theres always the chance of catching that lunker!

Don't those browns and brookies need a respite from the last six months of angling pressure? Why don't you give them a break and let them at least have time to propogate the future fish to populate or streams and rivers.

BTW most rainbow trout spawn in the Spring and not the Fall. Perhaps if you are seeing rainbows in the feeders they are followng the browns and brookies to eat their eggs.
