Keep Herp Calendar free

Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.

Plains Hognose Snake

Heterodon nasicus

Look, don't take. Many states regulate collecting reptiles and amphibians. Photograph it, log it on iNaturalist and leave it where you found it.

Description

The western hognose snake (Heterodon nasicus) is a species of snake in the family Colubridae. Its color and pattern is highly variable between subspecies, although most specimens appear much like rattlesnakes to the untrained eye, which appears to be Batesian mimicry.Wikipedia ↗

Habitat

The western hognose snake occurs from southern Canada throughout the United States to northern Mexico. It frequents areas with sandy or gravelly soils, including prairies, river floodplains, scrub and grasslands, semi-deserts, and some semiagricultural areas.Wikipedia ↗

When it's active

The western hognose snake is primarily diurnal. This is because hognose snakes' instinct is to brumate underground during the winter months.Wikipedia ↗
