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 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.

Hi all,
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.

Hi Steve-
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.
