Western massasauga rattlesnake

Sistrurus catenatus tergeminus


This rattlesnake has a row of dark brown blotches that run down the length of its back. It also has three small rows of lighter colored blotches along each side. This snake has keeled scales, a vertical pupil (not round), and an obvious heat-sensing pit between the eye and nostril.


Open prairie / cattle pasture


I chose Father's Day to do my very first road cruising of the season and it paid off. This snake was the first thing I found and it was less than 2 miles from my driveway. I like to get out on some rural county roads that are nothing more than gravel between fenced pastures. Sometimes I get lucky and find quite a few snakes.

I'm currently adding all my U.S. snakes to the mission at this time. I didn't realize how many snake spottings I had until now! :-)

Awesome spot Aaron!
We have a new mission for Snakes of the United States created by the Center for Snake Conservation that you might like to add this beauty & your other wild snake spottings to -

For my county it's a pretty good find, as they're found more to the west of me. This is #2 on my list of snakes I really want to see each summer. The one that still eludes me for my county is the timber rattlesnake. I've seen photos of a deceased one just a mile or two away from my house, so I know they're out there. They're just not in big numbers in this county.

Super! I love it! I've never seen one of these, as they are very rare and considered endangered in several states.
