Daddy-long-legs, like other spiders, are excellent hunters of small insects, such as mosquitoes. They also hunt other spiders, including their own species. There are commonly encountered in bathrooms. In corners of rooms, they build an unkempt net, in which they wait for prey, usually hanging upside down. When disturbed, this spider can shake its net so violently that it practically disappears from a potential predator's sight. It performs the shaking by shifting its weight from side to side. During the summer, females use their mandibles to carry a clutch of up to thirty grayish eggs, which they set aside only to eat. After hatching, the female guards the young for about nine days. Daddy-long-legs live for around three years.
