Conservation statusThis species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001). Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend is stable. Year assessed: 2007.
However, it is listed as endangered in the state of Iowa, and threatened in Illinois and South Dakota. It is more common in the southern end of its range, where holds no particular conservation status.
BehaviorThe Western Hognose Snake is primarily diurnal, and makes use of a variety of habitats, including shortgrass prairies, grasslands, and rocky, semi-arid regions. They are typically a docile snake, that may hiss and make mock strikes if harassed, and even play dead if stressed enough (but they will never bite in self-defense). They feed on amphibians, lizards, and rodents. They breed in the spring, laying 4 to 23 eggs in the mid summer, which take approximately 60 days to hatch.
ReproductionOviparous, with females laying 4-23 elongate, thin-shelled eggs in June-August. Hatchlings are 15-19 cm in length and reach sexual maturity after two years.
CaptivityThe Western Hognose is the hognose snake species which is most commonly kept in captivity. It is a small, hardy species with a docile nature that tends to make it an attractive choice for a pet. They readily consume commercially available rodents, and do not require a large amount of space or specialized care. They are often captive bred, and even color variations are being propagated, including high red, high orange, and albino variants.
TaxonomySome authors elevate H. n. kennerlyi, also known as the Mexican hog-nosed snake, to species level. Those same authors have subsumed H. n. gloydi into H. nasicus so that there are only 2 species (H. nasicus and H. kennerlyi) and no subspecies.
