This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.

Moth Family Geometridae
These are sometimes called Green Worms.
These terrestrial moths are sometimes taken by trout when their larvae, the well-known inchworms, dangle by their little silken threads in especially high numbers around June. They may be abundant enough throughout the forest that plenty dangle their way into the water.
I caught this inchworm lowering itself to the surface of a trout stream from its silk thread. I saw a couple others floating on the surface, so it's likely the trout were familiar with them.
