, agaves and the banana family. They are medium to large spiders, and are usually a grey, brown or orange color. Sometimes owning a striped pattern. They have relatively longer legs then their bodies.

Retreat

These spiders hide during the day then come out to hunt during the night. They are quite specific with their retreats. They usually hide in

, agaves and the banana family. If these leaves are exposed they would usually stick together leaves or make tunnels by bending or rolling up leaves and pasting them with silk. The inside of the retreat is usually more humid then the outside during the day, usually being at 90% humidity, as drying up is a considerable risk for them.

Hunting

They hunt at night, hunting in the plants leaf, rather than waiting in their retreat. They do this in what we consider total darkness. Instead of using their eyes to see the prey, they use small vibrations, which they may feel up to several meters away. Although the do still have advanced eyes. To feel these vibrations they have specialized organs called

metatarsal The metatarsal bones, or metatarsus, are a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes. Lacking individual names, the metatarsal bones are numbered from the me ...

lyriform organs. Which are located in the metatarsus of the two front legs. These organs consist of tiny slits, which are parallel to one another, looking like a lyre. When the tarsus is moved by the vibration, they compress, which stimulates the nervous system.

Courtship

These spiders own a very unique courtship system. Once it's time to breed the female will leave a dragline made of silk, wherever she walks to. Once the male recognizes the thread of the female, it will start sending vibrations to the plant the string was found on. Being distinct to each species. If the females replies, the male will follow the vibrations to the female.
