I'm having a difficult time trying to figure out what kind of caterpillar this is. It has a white line that runs down the center of its back. It also has what I would describe as eye markings that are blue and they run down both sides of it.

This snake was found inside the house. It also gave me the second snakebite I have ever received (at least that draw blood, I don't think a really mad garter snake counts). Its punishment? It had to let me take more pictures than I have taken of any other Coachwhip previously. I find myself fascinated with the eyes. The pattern (dark below the pupil, light above) is so unique. I noticed this in a previous observation but it's still interesting.
