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.

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 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.
