Aaron, Is this photo edited? If so, can we see the original. I think I see what might be a tail and Eyes, but it could be me just trying to see something other than just a segmented body. You mentioned you pulled it out of a rock with tweezers. How big was this?
Even if What I am trying to see is what I am seeing...It does not look like anything else I could find on Mantis Larvae. Perhaps a juvenile.
