Dorsal view of a Limnephilidae (Giant Sedges) Caddisfly Larva from the Yakima River in Washington

This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

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 was the hatch of the night on 25 May 2011. It was epic....yet nothing was rising or visibly feeding. Not really positive what it is. It could be a Hendrickson, it's just so dark and eyes are so red. All the bugs coming off had the same strikingly red eyes.
Thanks all

Male Ephemerellids of some type. Late for subvaria unless you are up north. Early for Seratella me thinks.

Where are you?
What size (hook size) were they?

If you click the "edit" link above your post, you'll see an option to attach your picture... that'll potentially help us with the ID.

I'm going to guess right now:

Serratella deficiens/tibialis -#16 chocolate dun with nearly black wings, pale legs, and red eyes on males.

If not such dark wings and a dark olive body then mebbe a Drunella.
