In Oklahoma, there is just one type of tarantula that is known to call the state home, the Oklahoma brown tarantula. This is a large spider, known for being docile around humans, yet a fierce hunter of other insects.

They have even been known to eat small mice and small snakes on occasion. These spiders are also frequently seen in other states across America, and in each of these regions, the name they are given varies.

Scientific name

The scientific name for the Oklahoma brown tarantula is Aphonopelma hentzi. However, this large spider has multiple common names that it is known by. This tarantula falls in the Theraphosidae family and Araneae order.

Common names for this insect depend on the state it is found in, but all of these tarantulas are the same spider. In any region where they are found, they may simply be called brown tarantula.

Other names

In addition to the common name brown tarantula, these spiders have multiple nicknames. They are also called Texas brown tarantulas, Missouri tarantulas, or Arkansas chocolate tarantulas. The name depends on the state this spider is found in, as they have a far-reaching range across North America.


Oklahoma brown tarantulas can be found living in burrows in wooded regions and the rocky terrain of the state. Not only do these burrows give them a space to hide from predators, but it is also where females will lay and guard their eggs.

Young tarantulas stay with their mothers for the first week of their life, but after that, they disperse. These large spiders are found in other states as well, including Missouri, Arkansas, and Texas. They are most active at night when they do most of their hunting.

This also helps them avoid certain predators. In Oklahoma, these tarantulas are mainly found in the southwest region of the state, but they can be spotted anywhere. They prefer to stay in dry areas.
