Texas Brown Tarantula Facts
“The Texas brown tarantula is a classic big hairy spider!”
Texas browns are one of the most common tarantulas in the US and are often called Missouri tarantulas or Oklahoma browns. Their bodies and legs are covered in brown hairs that give them a furry look. They have eight long segmented legs with two additional arm-like pedipalps at the front of their bodies. Texas brown tarantulas are terrestrial, living in burrows abandoned by other animals or digging one of their own. During mating season, it is more common to see them out and about.

Texas Brown Tarantula Scientific name
The scientific name of the Texas brown tarantula is Aphonopelma hentzi. There are around 1,000 different tarantula species with 30+ native to the United States. Tarantulas are some of the biggest spiders in North and South America. The Texas browns are sometimes called Oklahoma brown tarantulas or Missouri tarantulas depending on their location.
Texas Brown Tarantula Appearance
The Texas brown tarantula has a stocky build with a large abdomen and carapace. Their bodies are brown, and their eight legs are a bit darker. They have spikey, bristle-like hairs that cover their body called setae. Their bodies can be 2-3 inches with a leg span of 5-6 inches. That is longer than your average cell phone.
In addition to their eight legs, they have two appendages at the front of their bodies called pedipalps. They are used like arms for grasping prey and the males use them during mating. On the front of their head the Texas brown tarantula has a chelicera and eight eyes (ocular tubercle). Their vision is poor, so they rely on sensing movement with their bristly setae.
Texas Brown Tarantula Behavior
Texas brown tarantulas are easy going and predictable. They spend most of their lives in their burrows, which they either dig or take over from a previous animal. At night they head to the entrance of their burrows and wait for some unsuspecting insect, frog, or cricket to wander by.
If a Texas brown tarantula comes across a large lizard, the tarantula may flick urticating hairs off its abdomen at the predator. These hairs penetrate the skin, which is painful, deterring the lizard from attacking.
These spiders also molt, wiggling their way out of their skin, or exoskeleton, to make room for their growing bodies. During this time, they may refuse to eat, but afterwards they may have a hardy appetite.
Texas Brown Tarantula Habitat
It’s no surprise this spider lives in Texas, but they can also be found in Oklahoma, Missouri, Colorado, Kansas, Arkansas, Louisiana, and New Mexico. They are terrestrial, spending much of their time hidden deep in burrows in the ground. The entrance to their burrows is covered with a white silky web that keeps predators out and can help the tarantula detect movement of approaching threats.
The most common habitat of the Texas brown is arid desert, as they are equipped to deal with the dry climate. They are nocturnal animals that come out at night to look for food, but they’re occasionally out in the early morning or late evening as well. Tarantulas don’t wander far from their burrows; In fact, they usually stay home and wait for food to come to them. You might see more tarantulas in the fall when the males leave their burrows to find a mate. Otherwise, these creatures remain fairly hidden.
Texas Brown Tarantula Predators and Threats
Predators of the Texas brown tarantulas include lizards, snakes, coyotes, birds, and foxes. You may also be aware of tarantula hawks, the biggest wasp in Texas. These wasps are blue with orange wings and can get to be 2 inches long. They are common in much of the southern states of the US. If you have ever been stung by one, you know how painful it is. When they sting a tarantula, they have gruesome plans. The sting doesn’t kill the tarantula but paralyzes it. The wasp will then bury it alive as food for its young. The female lays an egg on the tarantula’s abdomen and when the larvae hatch, the first meal is readily available.
Texas brown tarantulas have a few defense mechanisms including urticating hairs they can flick at a predator. If they feel threatened, they can also try to intimidate a predator by taking a threat pose. When in this posture, they raise up, hiss, and show their fangs. However, they are not overly aggressive and prefer to flee than fight.
What Eats Texas Brown Tarantulas?
What Do Texas Brown Tarantulas Eat?
They eat insects, crickets, and roaches, but can also eat small lizards and mice. They don’t need to eat very often; In fact, they can go weeks without food, but when they do eat, they do so aggressively. If prey wanders by their burrow, the tarantula will snag it with its front pedipalps and wrap it with a web. It may use its fangs to inject venom that contains digestive juices to help liquefy the prey so it can suck up the nutrients.
What is the Conservation Status of Texas Brown Tarantulas?
Texas brown tarantulas are not listed by the IUCN as a threatened species. They are a common tarantula in most of the southern states in the US.
Reproduction, Babies, and Lifespan
Texas brown tarantulas are solitary animals, but when it comes time to mate, the males leave their burrows. This happens in the late summer or fall, when mass migration of tarantulas can be seen in some areas. These spiders venture off, looking for female tarantulas that are receptive to mating. They latterly knock outside the door of the burrow by tapping their leg on the ground. If the female is ready to mate, she comes out of her burrow and the male spins a sperm web. He deposits his sperm on the web and then uses his pedipalps to insert the sperm into the female.
The females can lay up to 1000 eggs at a time, which they keep in their burrows for safety. She makes an egg sac, which she watches for the next 45-60 days until the spiderlings hatch. Not all of the eggs survive and not all of the spiderlings make it to adulthood, as many are eaten when they venture out on their own. Spiderlings usually leave their mother’s nest a few days after hatching.
The life span of the females is much longer than that of the males. Females can live more than 30 years. Males, on the other hand, usually only live eight to 10 years.
It is difficult to get an accurate count of tarantulas due to the fact that they spend most of their times hidden underground. According to the National Park Service, there are 14 different species of tarantulas in Texas. They are not listed by the IUCN as a threatened species.
