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.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.

Specimens of the Stonefly Genus Alloperla
1 Female Adult
These little green stoneflies were the most common bug on a June day fishing the North Fork Couer d'Alene, although the trout never rose more than sporadically to them or anything else.
3 Adults
This specimen was completely green when I collected it from among many others gathered on a midstream rock along with their nymphal shucks early in the morning. There was also a yellow one with them, which I assumed was a different species. Now that I've seen how this one started changing from green to yellow, I have to wonder if they weren't the same species and the yellow one was just older.
At Touchet Corral.
