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.

Epeorus albertae (Pink Lady) Mayfly Nymph Epeorus albertae (Pink Lady) Mayfly Nymph

Dorsal view of a Epeorus albertae (Heptageniidae) (Pink Lady) Mayfly Nymph from the East Fork Issaquah Creek in Washington

This specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.

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.

Xavier_Carp-

If I were to hazard a guess, it would be that the 1st and 3rd photos might be of family Aeshnidae, and that the 2nd and 4th photos might be of family Libellulidae. Both families are most commonly collected along the edges of lakes and ponds. However, identifying dragonfly nymphs is much more difficult if photographed out of the water, and even more so, if they have not reached full maturity.

Hopefully, someone here will be more experienced identifying dragonflies, and can give you more than my admittedly lame guesses.
