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.

New to the site. I'm not a fisherman myself, but I do a lot of water quality monitoring and I've been making a concerted effort over the past year to become familiar with the various macroinvertebrates that live in streams, so I'm excited to see the wealth of excellent photos of them here. I have a small collection of some preserved specimens and thought I'd share a photo of one of them here - this is a helicopsycidae, or snail case-maker caddisfly that I found in one of the local streams last summer. Photo was taken using a Digimicro USB digital microscope. For scale, this guy measures about 1/4" across.

Interesting digital microscope, and the price is certainly right. I see it will capture a 1.3 MB image. However the image you posted (picture_281_full) is only 46 KB. Would appreciate your posting another image of your Snail Case Maker Caddisfly, which is just under Jason's 1 MB maximum, so I can more fully appreciate the capability of this scope.
