Arboreal tarantulas live singly in specially constructed silken tube webs or in crevices, behind loose bark or among epiphytic plants. The Trinidad chevron tarantula breeds freely in captivity. Two silken egg sacs are commonly produced from one mating and each of these contains one hundred to one hundred and fifty eggs. The female spider guards the sac, turning it occasionally, and the eggs hatch after about six weeks. The spiderlings usually disperse at the first instar stage.
