Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

I caught several wild and colorful 8-9 inch brook trout in the clear little pool below this waterfall.

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.

This is a water beetle. It is the hardest object in the world to pick up with tweezers. The second hardest is Mount Everest.

I'm not great on beetle identification, but this one seems pretty easy--Hydrophilus triangularis.

Thanks. I'm just going to put that ID in the description, rather than moving it into a section on that species like I usually do, because I don't have all the beetle taxa in the database. There are just too many of them.

DMM-

Thank you. I'm glad you like the book. But there's certainly no need for formal address. Gonzo is fine.
