This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

Can anyone tell me what these are?? Look like they were left by some sort of aquatic life. They were discovered about a month ago in the Maiden Creek, Kempton, PA. The weather at that time was still hot, and water in the creek was very low. Also, I believe the Maiden is a freestone creek, but I could be wrong. Thanks.

Those are Neophylax caddis cases. They are either pupal cases, and about to emerge as they are autumn emergers. If you had found them earlier -midsummer- they could have been in summer aestivation. Not all caddis do this.
They were a really common caddis in Central NY where I used to fish. Trout glean the larvae, case and all, from the bottom too. Gravel in trout stoamchs was often due to this.

The fourth one is a mud bug. Unlike the others, if you get enough the mud bugs can be real good eatin. I had fried Stenopsyche, a large Asian caddis, one time, and they really don't come close to matching mud bugs.

Dave,
I believe the mudbug (crayfish) photo was on a different thread.

Hey, Creno-
What's the overall geographic distribution of Stenopsyche? Your comments reminded me of some collections I made about twelve years ago that I have not gone through for awhile.

Konchu - I really don't know their distribution and am traveling so cannot readily look it up. I know they are eastern Eurasian from India to Japan and Eastern Russia. I haven't heard of any making it to NA and I don't know how far south and west in eurasia they go. Was looking at a Eubasilissa today (a phryganeid)and that would be a real meal - three/4 times the size of Stenopsyche.
Roger - wonder how I did that? Hit reply and end up in a different tread. Oh-well.

Hi Dave,
Yes, I can certainly relate given some of the things my mouse has accidentally succeeded in accomplishing, not the least of which was to lose all of my saved-sent-email before (also accidentally) discovering where it had gone.

Those were Japanese caddisflies I was talking about, so it is possible, then.
