無害對人無害。不用擔心。

會螫人的毛吃：植物

The garden tiger moth is a moth with bold patterned wings that warn predators it is unsafe to eat. It lives in cool, temperate parts of the northern United States, Canada, Europe and Asia. Its caterpillars are known as 'woolly bears' because of their fuzzy look.1

在陸地上, 粗略估計

牠吃什麼？

The caterpillars are generalists and eat many different plants, from foxglove and members of the daisy family to plantago. Adults do not feed at all and live only on energy stored during the caterpillar stage.1

毒液力量

會螫人的毛

細小的毛或刺毛會斷在皮膚裡，造成刺痛。

牠的毒液有什麼作用？

This moth does not inject venom. Its body fluids are poisonous and contain neurotoxic choline esters, which are nerve-affecting chemicals that interfere with the acetylcholine receptor. The full effects of these toxins are not yet known. Caterpillars have hollow hairs that often contain irritating compounds.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。

牠害怕時會做什麼？

When threatened, adults can spray an irritating compound from glands that are exposed at that moment, and their bright wing patterns warn predators.1

如果你碰到牠的毛

被會螫人的毛毛蟲毛刺到時：用膠帶把毛黏起來，再清洗皮膚。不要搓揉。
被咬時：清洗並冷敷。如果傷者覺得不舒服或容易流血，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。
如果你碰到牠的毛：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

Adults can make rasping sounds with their wings and high-pitched squeaks that people can hear, and bats tend to avoid them.1

Caterpillars can break down the toxins in their host plants and reuse them in altered form for their own protection.1

The French entomologist Oberthür described about 500 different wing pattern and colour variants.1

Adults are mostly active at night, from June to September.1
