Mystery Water Bug - Caecidotea

Mystery Water Bug - Caecidotea
Benton County, Arkansas, USA
March 21, 2014
Size: about 1.5 cm
I found this bug in a small, shallow pool in the woods that is full of decaying leaves. The pool is only there if there has been a bit of rain. I have kept him for short term observation, and added decaying leaves to the bowl I am keeping him in. Since he is almost transparent, I can see the food in his digestive system, and it appears that there is more food there than when I first got him. This leads me to think his food source has something to do with the decaying leaves. I am going to guess that he is some sort of aquatic larva.

Moved from Asellidae.

Determination by G.O. Graening.

In addition to hearing from Dr. Graening, Christopher Rogers of the Kansas Biological Survey has volunteered to look at your specimen. In order to get a species ID, the specimen will need to be examined microscopically. I can put you in touch with Christopher -- just say the word.

That would be great. I still have the specimen alive and under observation. How would you like me to proceed?

I've contacted a buddy who specializes in crustaceans to take a look at your photo. I take it your specimen is still transparent? Is this locality near a cave?

Yes, my specimen is still tra
Yes, my specimen is still transparent. There are no large caves that I know of in the vicinity where I found him, but there are some fissures in the rocks of the bluff there. The pool I found him in is actually formed from water running out of one of the fissures.
