This is the eastern dobsonfly larva, also known as a hellgrammite. I always assumed they were solely aquatic. Apparently, I was mistaken. I found this one under a rock in the cave while I was looking for salamanders. The cave was completely devoid of water. I read this detailed account of the eastern dobsonfly and found out the larva is capable of existing in or out of water. Until now, I had only seem them in streams.
