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 one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

I added several new bugs I collected this week to the site tonight, including this caddisfly. Anybody care to ID it?
To view all the new specimens, go to any page of this site outside the forum section (like the homepage) and look under "recent updates" in the left column.
I'll be adding some even better bug pictures tomorrow from a collecting trip a couple days later.

Jason,
I was on a stream the other day in the driftless area and i found a couple of caddis on some of the rocks. They looked exactly like this one does but for their casing it wasn't used with little rocks, it was the wood type casing. -(brownish black) the caddis had a green body and a head like that one..

Lots of cased caddisflies look similar to this, with the green body and dark head. You often have to get into trickier anatomical details to figure out the genus, or even the family.
