它吃什么？

It hunts mainly at night, when many insects are less active. It creeps up on its prey, measures the distance with one front leg, then squeezes its body and spits two silk threads in a zigzag over the victim. Larger prey may be spat on several times.1

值得了解

事实

It spits two silk threads in a zigzag pattern in about 1/600 of a second.1

Its silk glands in the front of the body (cephalothorax) are linked to its venom glands, so it can make venomous silk.1

It stops about 10 mm from its prey and measures the distance with one front leg before it spits, so as not to disturb the victim.1

It is thought to find prey using long hearing hairs on its legs.1
