One of two spcies of Boidae native to the united states, L. trivirgata is an uncommon sight in the canyons of the Mojave. Found occupying rocky, granitic outcrops, these snakes are almost obligately ambush predators, being too slow moving to hunt down and capture prey. Like all members of Boidae, these snakes are non-venomous constrictors, capturing prey and
suffocating it by progressively tightening its body as the prey exhales.
They tend to be active during the warmer parts of the day, while staying under shelter during the hottest and coldest times of the year. These boas, like most members of the family, are ovoviviparous, giving birth to live young, usually in broods of six.
