The Rosy Boa or Lichanura trivirgata is also one of snake from the Boidae family, one of only two members of that family native to the United States. The other is the Rubber Boa or C. bottae.
Most Boas do not have this ventral coloration but instead have a series of dark to orange spots on a light-colored background.
Almost all Rosy Boas have at least some trace of three longitudinal stripes, one down the center of the back, and two on the lower sides. The appearance of these stripes varies widely from extremely straight and having high contrast with the inter spaces to extremely broken with almost no contrast with the inter-spaces. Stripe colors can be orange, maroon, rust, brown, or black. The inter-spaces range from shades of light to dark gray, yellow, or tan.
