The desert rosy boa (Lichanura trivirgata) is a species of snake in the family Boidae. The desert rosy boa is native to the American Southwest and Baja California and Sonora in Mexico. The desert rosy boa is one of four species in the boa family native to the continental United States, the other three being the coastal rosy boa (Lichanura orcutti) and the two species of rubber boas (Charina).
Edward Drinker Cope described the species in 1861. The specific epithet trivirgata refers to the distinct three stripes characteristic of the species. Some researchers have placed the species in the genus Charina with the rubber boas (see Synonyms). Newer phylogenetic research supports the original arrangement, but herpetologists still do not agree on rosy boa taxonomy. Wikipedia →

With luck
About 10% of wildlife watchers report a Rosy Boa sighting in El Vizcaíno Biosphere Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 20 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
November
In that month about 40% of wildlife watchers report a Rosy Boa in El Vizcaíno Biosphere Reserve on a given day, against under 5% in July–September and December–April, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Rosy Boa sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only El Vizcaíno Biosphere Reserve, in our data
El Vizcaíno Biosphere Reserve is the only park on Wallace's Line with enough records to rate Rosy Boa sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Rosy Boa is recorded against all the reptiles logged in El Vizcaíno Biosphere Reserve (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
