Lichanura trivirgata
A small boa of the rocky deserts of the south-western United States and north-western Mexico. Named for its three longitudinal stripes, it is one of the slowest-moving snakes in the world and its docility makes it a common beginner species.
Lichanura trivirgata is a boid of the arid south-western United States and north-western Mexico. Total length ranges from 43 to 112 cm and varies considerably by subspecies and locality. Almost all individuals carry three longitudinal stripes, one down the spine and one along each flank, but their sharpness varies enormously and their colour ranges through orange, maroon, brown and black. It spends most of its life beneath rocks and in crevices, most often in granite outcrops. It brumates through winter and is most active in the spring breeding season, turning nocturnal in hot weather. One of the slowest-moving snakes in the world, it cannot chase prey and instead ambushes or stalks it before constricting. It is extremely docile, and when disturbed it rolls into a ball and releases foul-smelling musk rather than biting.

Target a basking surface of 29-32 C and a cool zone of 24-27 C. Turn the heat off at night; temperatures can safely fall to 16 C. Keep humidity below 60 percent, measured with a digital probe hygrometer in the middle of the enclosure, as sustained high humidity makes them unwell.
Size the enclosure as snake length x half length x half length: 60 x 30 x 30 cm for a 61 cm animal, 120 x 60 x 60 cm for one that reaches 112 cm. Front-opening enclosures are easiest to service. Provide 7.5-10 cm of sand or sandy soil so it can burrow, plus several rocks and hides.
In the wild it takes mainly rodents, along with lizards, amphibians, other snakes and birds. In captivity offer thawed frozen mice sized to the snake, warmed to about 38 C, using soft-tipped feeding tongs.
Extremely docile and rarely inclined to bite. When disturbed it balls up with the head in the centre and releases foul-smelling musk from the tail base. Its slow movement and small size make it an easy first snake. Keep it singly.
As a desert species it should never be kept on permanently damp substrate. Its taxonomy is unsettled and coastal populations are treated by some authorities as a separate species, Lichanura orcutti, so confirm locality claims with the seller. Listed on CITES Appendix II as Boidae spp. since 4 February 1977, so no registration certificate is required. The IUCN Red List assesses it as Least Concern.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Rosy Boa is 24〜32℃. Recommended humidity is 60%. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Rosy Boa is 20-30 years. With proper care and nutrition, they can live a long and healthy life.
Rosy Boa typically reaches 43-112cm as an adult. Size may vary depending on care conditions and individual genetics.
Rosy Boa feeds on: Thawed frozen mice. Aim for a balanced diet with appropriate feeding frequency.
