(Bogertophis subocularis, p. 384 + Plate 35).
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. There is an isolated locality of B. subocularis where it is found with a light yellow coloration that is termed a "blonde" variant, and there is also an almost white coloration, that is sometimes referred to as the "silver" variant.
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 Bogertophis species are oviparous.
In captivity Both Bogertophis species are commonly available in the exotic pet trade. Due to their typically docile nature and reliable feeding habits, they can make an excellent choice for a captive snake. They are also well represented in zoos.
