European garden spider
The European garden spider is a large orb-weaver that spins round webs. It is native to Europe and was introduced to North America. Its white markings form a clear cross on its back, which is why it is easy to spot in the right place.1

怎麼認出牠
- Mottled white markings across the upper abdomen form a cross made of four or more segments.1
- Body colour ranges from extremely light yellow to very dark grey.1
- Adult females measure 6.5 to 20 mm in length. Males are smaller, at 5.5 to 13 mm.1
- Females hang head down in the centre of a round orb web, with one claw hooked to a signal line.1
毒液力量
咬的時候,毒液會從毒牙或牙齒出來。
牠的毒液有什麼作用?
The bite paralyses prey, which keeps the spider safe from being stung or bitten in return. Enzymes in the venom start to liquefy the prey's internal structures.1
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。It is reclusive and only bites people when cornered or provoked.1
牠害怕時會做什麼?
When disturbed, it vibrates rapidly in its web until it becomes a blur, which is thought to confuse predators.1
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

小知識
Females sometimes eat the male directly after mating.1
The cross-shaped markings are formed in cells filled with guanine, a by-product of protein metabolism.1
Spiders also prey on each other, but only just before, during or after mating. Their size, mating experience and hunger affect whether they attack.1
