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 Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.
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.

I photographed this 1/4" nymph on a small mountain southeastern U.S. trout stream in April. What species is this?

Hi Higherroad-

Welcome to this site. That is a truly gorgeous photo. Although it might help if you identified it to the Southeastern state of origin, I suspect it to be a freshly molted nymph of Heptagenia marginalis.
Best regards,

How did you paint those little white bands so accurately on a little 1/4" long nymph. That is amazing.

That sure is a pretty little creature!

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

That is probably one of the wisest comments you have ever made on this forum.

God is great !!! And he is the greatest artist of them all. Our creativity stems from his work as an extension of everything we are.


On the contrary, science views things like this as the spectacular, inevitable result of nature left to run its own course. Just like mathematical fractals produce patterns more intricate than any artist could dream up, natural selection reshapes organisms in more varied and impressive ways than any one being could imagine, let alone control. Nature needs no guiding hand to impress.

Beautiful. This looks to me like some freshly molted Rhithrogena that I've seen from the SE. The spots on the femora aren't as prominent as usual, but I think I can make them out.

I wonder what drove the development of such a pigment scheme? It has a story to tell.

There are several species out West noted for similar color schemes. Anecdotally, I've noticed they seem to inhabit the salt & pepper granitic substrate of many West Coast streams. There is one species of ephemerellid with virtually the same color scheme called Attenella delantala. The very distinctive marks had me stumped until Roger (Taxon) schooled me on it several years ago. I had never seen one before but they are supposedly fairly common out here.

Various Drunella species worldwide show that scheme, too. And actually several baetids show it, too, such as Plauditus cestus et al.

Yes, the D. grandis subspecies are good examples.

Reminds me of the very young larvae of giant swallow tail butterflies.

Google images of "larvae of giant swallowtail butterflies "

They mimic the poop of small birds as they crawl around on the foliage of their food. It does not seem that looking like bird poop would help these guys UNDERWATER, but it's a thought.
