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.

Dorsal view of a Grammotaulius betteni (Limnephilidae) (Northern Caddisfly) Caddisfly Larva from the Yakima River in Washington
This is a striking caddis larva with an interesting color pattern on the head. Here are some characteristics I was able to see under the microscope, but could not easily expose for a picture:
- The prosternal horn is present.
- The mandible is clearly toothed, not formed into a uniform scraper blade.
- The seems to be only 2 major setae on the ventral edge of the hind femur.
- Chloride epithelia seem to be absent from the dorsal side of any abdominal segments.
Based on these characteristics and the ones more easily visible from the pictures, this seems to be Grammotaulius. The key's description of the case is spot-on: "Case cylindrical, made of longitudinally arranged sedge or similar leaves," as is the description of the markings on the head, "Dorsum of head light brownish yellow with numerous discrete, small, dark spots." The spot pattern on the head is a very good match to figure 19.312 of Merritt R.W., Cummins, K.W., and Berg, M.B. (2019). The species ID is based on Grammotaulius betteni being the only species of this genus known in Washington state.
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.

Hello all, I'm new to this forum and would appreciate some advice. I am currently in the market for a 4,5,or 7 piece "travel rod" in 4 or 5 weight. I have looked at the cabelas stowaway 5 piece and the Bass Pro Shop Hobbs creek brand oufits. Has anyone had any experience with either of these? I fish mainly the tail waters of East TN and the Smokies. Thanks in advance for the help.

Zipper, try the Cabelas Three Forks 4-piece rods. I have their 4-piece 8 1/2-foot 5-weight (old version, moderate action) and I love it - especially since I only paid $55 for it (two years ago - it's now $60-65, but check their website since they're having some sales including reels and lines, you can get a good deal on a whole outfit). I have been a fly rodder for 23 years and I can really throw well on this rod - it has a little extra snap when I go to shoot line that lets me really punch them out there. They've apparently updated the action to moderate-fast and I haven't tried the new ones yet, but for the price the rod that I have is a rediculously good deal. If I were you I would try to handle one before you buy it to see just how it feels to you, depending on what kind of rod action suits you best.

Hope this helps!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
