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 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.

If you've still got it, could you take a pic with it in the water, under a bright light but without the flash? Getting in closer if possible would also help a lot.
It's really hard to make out the important details of nymphs or larvae out of the water. Caddis larvae look as strange dry as a cat does soaking wet.
