Dorsal view of a Skwala (Perlodidae) (Large Springfly) Stonefly Nymph from the Yakima River in Washington

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.

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.

John - Might be an Orange-striped Oakworm, not really a worm despite the common name. Here's a link with the latin name and a good photo.

John, as far as I know bacillus thuringiensis is one of the best controls for caterpillars. It's a targeted biological control, and thus less of a risk for many other creatures.

Thanks for the info guys. My boys have come up with a great control method as well. They pull the caterpillars off the tree gathering as many as they can and then feed the neighbors laying hens. No pesticides or chemicals needed (although the "worms" do not like Sevin.
