While herping in a glades habitat in Missouri, we came across this awesome arachnid. It is one of the most common species of tarantula living in the southern United States.
The Texas Brown Tarantula is a stocky, hairy species and is Missouri’s largest spider. The body and legs are uniformly dark chocolate brown, with reddish hairs on its back.
This species is commonly found in grasslands, in underground burrows, or using logs, stones, or other small animals’ abandoned dens as their homes and feeding grounds.
Like many hunting spiders, tarantulas are nocturnal, pursuing insects such as crickets and beetles. Like other spiders, they have fangs that deliver a venom that both subdues their prey and helps digest it. They are not dangerous to humans and tarantulas prefer areas seldom frequented by people.
Texas Brown Tarantulas use their spinnerets to line the entrance of their shelters with webbing to detect passing prey. In this photo the spider’s shed exoskelton is outside of its burrow entrance.
Though it is not aggressive, like any frightened animal, it will defend itself if it feels threatened. Running for cover is its usual response after being spotted.
This is a relatively long-lived creature. Most males do not live for more than a year, however some females can survive up to three decades. This Texas Brown Tarantula was the first adult example I’ve ever encountered and was a welcome find on our herping trip.
