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.

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.
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.

Down at the Russian River today and some of the critters are back. Actually,
most have been in the river for about two weeks. Some of the animals are Acentrella insignificans, Ameletus sp., probably a female Capnia umpqua and Taenionema pacificum.

The Ameletus is just about the most gorgeous mayfly nymph I've ever seen. Great photos!
