Dancing white lady spider

Leucorchestris arenicola

無害對人無害。不用擔心。

咬吃：肉

The dancing white lady spider is a huntsman spider that lives in the sand dunes of the Namib Desert in Namibia. It hides in burrows during the hot day and comes out at night, when it can tap on the sand to send messages to other spiders.1

Bare sand dunes in the Namib Desert. Each spider lives in a silk-lined burrow dug into the sand, with a territory of about a 3 metre radius around it. It stays in the burrow by day to avoid the heat of the sun.1

在陸地上, 粗略估計

牠吃什麼？

It eats a wide range of insects, arachnids and reptiles, mostly nocturnal prey such as beetles, moths and weevils. It uses a sit-and-wait strategy, staying in its territory until prey arrives. Larger males sometimes eat other spiders.1

怎麼認出牠

Creamy white in colour1
Body length up to 32 mm1
Males have leg spans up to 14 cm and are lighter in weight than females1
In males, 5 to 8 legs have a median tibia dorsal spine, a small spine on the leg; in females it is seen on no more than 4 legs and is rarely present1
Active at night only, wandering over the sand1

常被誤認為： It is often mistaken for the wheel spider (Carparachne aureoflava), which has a similar name and lives in the same area. They are different species.1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

如果牠咬人

清洗咬傷處，用冰敷袋冰敷止痛。如果很痛、疼痛擴散或傷者覺得不舒服，要就醫。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

值得知道

小知識

The spiders communicate by tapping their front legs on the sand. This seismic signalling is called drumming.1

Males may be attacked and killed by females if their drumming signal is too much like that of prey.1

Males can travel more than 50 metres in one night while searching for a mate.1

Each spider has eight eyes arranged to give a full panoramic view of its surroundings, which is unusual for spiders at night.1

Burrows can be up to 40 cm long and 25 cm deep, and their shape keeps them cooler than the surface.1

Females live about 6 months, while males live only 1 to 2 months.1

破解迷思

迷思： It is the same spider as the wheel spider

真相： It is often confused with the wheel spider, but they are different species, even though they live in the same place.1
