Broad-banded Copperhead

Agkistrodon laticinctus

venomous
Venomous. Do not handle. Give it room and let it move on. If you're bitten, call 911 or go to an emergency room. Don't cut, suck or ice the bite.
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

Agkistrodon laticinctus, commonly known as the broad-banded copperhead, is a venomous pit viper species, formerly considered a subspecies of Agkistrodon contortrix, which is found in the central United States, from Kansas, through Oklahoma and throughout central Texas. The actual color varies, by locality, from a red-brown, to a gray-brown.Wikipedia ↗

Habitat

The broad-banded copperhead (A. laticinctus) is endemic to North America, where it occurs in the South Central states of Oklahoma and Texas in the USA, and the adjacent margins of the Mexican states of Chihuahua and Coahuila. It ranges from north-central Oklahoma, south to the Edwards Plateau in Texas, and west into southern counties of the Trans-Pecos region of Texas, including Brewster, Jeff Davis, Pecos, Presidio, and Terrell counties.Wikipedia ↗

When it's active

They are ovoviviparous, giving birth to a litter of up to eight young in the early fall.Wikipedia ↗

Venom

Like most pit viper species, A. laticinctus has a hemotoxic venom, which is delivered through hinged, hollow fangs set in the front of their jaws. Copperhead venom is not considered to be life-threatening to an otherwise healthy adult, but it can cause localized swelling, necrosis, and severe pain.Wikipedia ↗

Harmless look-alikes

Central Ratsnake, Western Ratsnake, Red Cornsnake, Great Plains Ratsnake, Common Watersnake, Eastern Hognose Snake, Eastern MilksnakeThough superficially resembling the venomous copperhead (Agkistrodon contortrix) and often killed as a result of this mistaken identity, the corn snake lacks functional venom and is harmless to humans. Wikipedia ↗Corn snakes can sometimes be confused with venomous southern copperheads (Agkistrodon contortrix), but the two can be differentiated by the narrower head, lighter coloration, and square-shaped spots that are found in red corn snakes.
