在陆地上, 粗略估计

它吃什么？

It eats insects, other spiders and small invertebrates. Unlike many spiders that wait for prey to blunder into their webs, it often leaves its web to hunt spiders and their eggs. When prey is scarce, both males and females will eat each other.1

怎样认出它

Small body, about 6 to 10 mm long in males and 7 to 8 mm on average in females, not counting the legs.1
Eight very long, thin legs covered in fine grey bristles. The legs are about 5 to 6 times the length of the body.1
Translucent grey or pale brown body, with a dark spot on the back of the front body part and dark, blurred spots on the top of the rear body part.1
Eight eyes: a pair of small dark eyes at the front, followed by three rows of pairs of larger eyes.1
Loose, horizontal webs with many irregularities, often tangled with the webs of other spiders.1

常被误认为： It is often called 'daddy long-legs', a name also used for crane flies and harvestmen. Crane flies are insects, and harvestmen belong to a different group of arachnids (the order Opiliones), so they are not spiders.1

值得了解

事实

It hunts redback spiders, which are among the most venomous spiders in the world.1

It fakes the vibrations of a trapped insect in its web, then waits on its long legs until the prey touches one of them before attacking.1

Its whirling defence can last several hours or even days when it is threatened by jumping spiders.1

Its silk has been reported to have potential medicinal uses.1

谣言粉碎机

谣言： Daddy long-legs spiders cannot bite humans because their fangs cannot get through human skin.

真相： Their fangs are about 0.25 mm long, and human skin is about 0.1 mm thick, so they can bite. Bites are very rarely reported, and they cause only mild stinging.1
