會螫人的毛吃：植物

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

The Io moth is a colourful moth from North America. Its adults are striking, with large eyespots on their wings. Its green caterpillars carry spines that release a very painful venom, so they should be left alone.1

在陸地上, 粗略估計

牠吃什麼？

The caterpillars eat the leaves of many host plants. Adult moths do not eat, as they have vestigial mouthparts.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？

The spines of the green caterpillars release a very painful venom at the slightest touch. Contact is not life-threatening to humans, but it irritates the skin and causes an acute skin inflammation called erucism.1

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

Contact with the spines is not life-threatening to humans, but it causes painful skin irritation.1

牠害怕時會做什麼？

When sitting head-down or when touched, adults shake and expose their hindwing eyespots. Caterpillars defend themselves with stinging spines.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

牠有多快？

Io moth 大約 0,03 km/h (0,02 mph)

一隻花園蝸牛 大約 0,05 km/h (0,03 mph)

一隻陸龜 大約 0,3 km/h (0,19 mph)

值得知道

小知識

The caterpillars' spines are urticating, meaning they can cause a stinging reaction on contact.1

Adults live only 1 to 2 weeks and do not eat during this stage.1

After emerging from the cocoon, adults inflate their furled wings with fluid pumped from the body, which takes about twenty minutes.1

Females attract males by releasing wind-borne scent chemicals (pheromones) from a gland at the end of the abdomen.1

Many flies and wasps are parasitoids of this moth, laying their eggs in or on it.1
