Aphonopelma hentzi, the Texas brown tarantula, (also known as Oklahoma brown tarantula or Missouri tarantula),[2] is one of the most common species of tarantula thriving in the southern-most United States today. Texas brown tarantulas can grow in excess of a four-inch leg span, and weigh more than 3 ounces as adults. The body is dark brown. Shades may vary between individual tarantulas and are more distinct after a moult.
Life cycle
Female A. hentzi can lay up to 1,000 eggs. The eggs are positioned securely in a web, which remains in the tarantula burrow, and guarded by the female. Eggs hatch in 45 to 60 days. Once spiderlings leave the egg sac, it is not unusual for them to stay with the females for up to a week or possibly longer before dispersing to make their own burrows.
Females have been known to live up to 30 years. But considering no studies have lasted so long, the lifespan is presumed to be longer. Males rarely live over 1 year after they have matured.
Habitat
A. hentzi lives in North America throughout Arkansas, Texas, Oklahoma, southern Kansas, Missouri, northwestern Louisiana, and other adjoining areas in the U.S. and northeast Mexico.[2][3] The spider can also be found in Colorado, and has been observed as far north as Denver.[4] They are commonly found in grasslands, burrowed under ground; or using logs, stones, or other small animals' abandoned dens as their home and feeding grounds. Texas brown tarantulas will use their spinnerets to line the entrance of their shelter with webbing so as to detect passing prey. Tarantulas are often restricted to the ground but can climb.
Defense
When disturbed, like most other tarantulas, A. hentzi will maneuver itself to a stance on its hind legs and raise its front legs in a threatening manner. Also, Texas brown tarantulas have small coarse brown and/or black urticating hairs on their abdomen that they will kick in the direction of whatever they may feel threatened by. Bites from the Texas brown tarantula are generally not a serious harm to humans. Apply a cold compress to the area, and if swelling or a rash occurs, seek medical attention.
