This hairy species is Missouri's largest spider. The body and legs are uniformly dark chocolate-brown, with reddish hairs on the carapace. The tarantula's large size and shaggy appearance is frightening to many people, leading them to believe it has a ferocious nature. It actually is a shy creature, quick to evade humans. Tarantulas are typically at home in areas seldom frequented by people. In late summer and fall, south Missourians often see these large arachnids crossing roads. This wandering phenomenon has been documented in male tarantulas in southern california, but it has not been studied in Missouri.
