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.

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.

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.

Grayling.
That would have been my uneducated guess, but I've never seen one before and I thought these might be some European fish I'd also never seen before. Thanks, Louis.

Thanks for the reply guys!
Slovenia is one of my favorite places to go fishing for grayling and trout. I know many flyfishers there and this year i`m invited to fish the opening of the "huchen" season. The huchen is in fact the donausalmon, a salmonite of the danube or donauriver.
I would really love to come over one day and fish in Montana but it`s quite difficult... prices are quite high for us in the states!
You can als see some of the Belgium rivers on my website, just to give you an idea about my country and the nature there...

If ever one of you is coming over here to Europe, you`re always welcome and.. warn me about it and i``l invite you.. we`ll fish together!!
Kind regards from,

Hi Luc,
Great pictures! I've always wanted to fish Slovenia, because the pictures I've seen are so amazing and because I'm half Slovenian. I won't be there anytime soon but it'd be my top choice in Europe.

Awesome pics! thanks. Hey Luc maybe you can answer this-- I spent some time in Bosnia and fished the Neretva river a few times. Some of the locals described to me a large predatory game fish, very aggressive. I could never figure out what kind of fish it was. Do you (or anyone) care to venture a guess?

Luc384 on Oct 9, 2007October 9th, 2007, 11:32 pm EDT
Yeah sure,
that's the "huchen alias donausalmon" this is family of the taimen you will find in Mongolia!! They are frequent in those rivers, also in Slovenia there are a lot of them in Sava, Savinja, Idrisjka, Baca.... But don't forget that there are also very big Marmorata trout there!!
The season opens now from 15 november untill end february. I'm invited by my slovenian friends to fish them on the Sava and Savinja river this year! Pictures of those fish you can find on my website under "foreighn rivers"

This thread made me curious and I googled Mamorata Trout. They sound very interesting. Here's a list that I ran into while googling. There are a lot of trout out there I've never heard of. So many fish, such little time:
A member of the salmon family (salmonidae), there are about 18 different families of trout. They are divided into three genus:
Genus Salvelinus (Char)
Lake Trout
Silver Trout (Extinct)
Brook Trout
Bull Trout
Aurora Trout
Dolly Varden Trout
Genus Salmo
Brown Trout
Flathead Trout
Marmorata Trout
Sevan Trout
Ohrid Trout
Adriatic Trout
Genus Oncorhynchus
Apache Trout
Rainbow Trout
Golden Trout
Gila Trout
Cutthroat Trout
Biwa (or Masou) Trout

The access to Slovenia is (for us) very good! We only need id card to enter. Roads are very good, nearly new. People are very kind and helpfull and prices are very low there! Most of the rivers are cristal clear and contain a good population of trout and grayling!
