The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

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.
