Species Description

Western Pygmy Rattlesnakes are often a pale gray with less spots than the Dusky or Carolina Pygmies. Their dorsal stripe is also a bronze or dull orange color compared to the red of their sister subspecies. They prefer a variety of habitats across their range, in Arkansas they are associated with cedar thickets, in Louisiana and east Texas they are found in dry pine uplands, and in Tennessee they are found around the edges of lakes and swamps.

This subspecies has faced severe range declines in East Texas, Missouri and Louisiana due to habitat loss and possible human persecution.

Like all Pygmy Rattlesnake subspecies, they target a variety of prey including amphibians, lizards and rodents. Young are born with yellow-tipped tails to assisting in luring prey.
