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.

Sunlight perfectly strikes the trees at a bend in the Foss River in the Washington Cascades.

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

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.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

My latest work project: fish & bugs

Jmd123 has attached these 20 pictures. The message is below.

Creek chub, lots of these (Semotilus atromaculatus)

Beautiful longear sunfish (Lepomis megalotis)!

Bluntnose minnow (Pimephales notatus), most common fish in our samples

Juvenile hog sucker (Hypantelium nigricans), only got one but I'm sure there's more

We caught 4 species of darters, this is probably an orangethroat darter, Etheostoma spectabile (the others were Johnny, fantail, and rainbow darters)

Weeeee little catfish! Yellow bullhead (Ameiurus natalis)

And now for some bugs! A raw, unsorted sample, separated from the debris

Paraleptophlebia was the second most common taxon after Chironomidae (which I may yet take down to genus!) Collected over 1100 of these total!

Ephemera was the largest mayfly we found

Chimarra was easy to spot because of their big heads!

Hydropsyche larva - Cheumatopsyche was much more common

Goniobasis snails were extremely common in some samples (one had 376!)

Not a mollusk nor a turtle! Water penny beetle larvae, Psephenus sp.

Here's (some of) what we collected! Remember, this is NOT a big stream, which made the diversity all the more surprising. Enjoy!

Note: all fish were identified, measured, weighed, and checked for health conditions such as parasites, lesions, sores, etc.

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

That is so cool. This is your job?!? Man, talk about doing what you love. This is what I'm constantly telling my kids. Find something you love and are passionate about and do it.
