Butler's Garter Snake is locally common, but rare or absent in some parts of its range. It generally prefers open, prairie-like, grassy areas with water or at least some moisture.
When excited or threatened this snake often thrashes about from side to side with little forward movement. Some observers find this a useful trait in identifying the Butler's Garter Snake in the field.
