Description.

"B. rosaliae" is more variable in color, found in shades of tan, red, orange, or brown.
"B. subocularis" is almost universally tan in color with interconnected black blotches on the back and two black stripes down the neck.

Behavior and diet.
"Bogertophis" are typically nocturnal snakes that feed on a wide variety of rodents, bats and sometimes lizards, especially when younger. They are found in semi-arid habitats; so they spend much of their time hiding from the heat of the day.
Reproduction.

In captivity.
