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.

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.
Best regards,

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