The Costa Rican Tiger Rump Tarantula (Davus fasciatus) is a striking and vibrant species of tarantula native to the tropical forests of Costa Rica and other parts of Central America. As its name suggests, this tarantula species is known for its distinctive tiger-like markings, featuring bold black stripes against a background of orange or reddish-brown hairs. These markings serve as a warning to potential predators, signaling the tarantula's venomous nature. Despite their fearsome appearance, Costa Rican Tiger Rump Tarantulas are relatively docile and can make fascinating pets for experienced tarantula keepers.

One interesting aspect of Davus fasciatus is its burrowing behavior. In the wild, these tarantulas create elaborate burrows in the soil, using their powerful legs and fangs to excavate and reinforce their underground retreats. This behavior is also observed in captivity, where they often spend much of their time hidden away in their burrows, emerging at night to hunt for prey. Costa Rican Tiger Rump Tarantulas are opportunistic feeders, preying on a variety of insects and other small invertebrates. Their venom, while potent enough to subdue prey, is generally not considered harmful to humans, causing only mild discomfort at worst. With their striking appearance and intriguing behaviors, Davus fasciatus is a popular choice among tarantula enthusiasts looking to add a touch of the tropics to their collection.
