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.

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.

If you haven't done so check out www.discoverlife.org...It's a general biology site but there are some interesting photos you can click on and enlarge of mayflies, stones, and caddis. There are other aquatic insects like damsels and dragonflies, and insects in general that may fall in to the stream from time to time. These phots found there like Jason's here are good models when you are working at the vise. If you are like me and like to mix up your own special dubbing colors these can be a great help.

Nice, Spence. Interesting stuff.

The only problem boys is they don't list the measurements of the bugs...I could use this bit of info. Some of the flies listed from New Hampshire, for example, have cousins here in Michigan.

The photos are great though and not just those of the aquatics.

Here is a bug site I found a couple of years ago that be of some interest. Once you open the web site you can click on any picture and it will enlarge. You can keep clicking it and the image gets bigger and bigger. Great detail with virtually no out of focus images.
