Local Habitat
Wet areas in old fields, meadows, pastures, and the open margins of marshes and streams.

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.
