Saddleback caterpillar

Acharia stimulea
只是會痛不要碰會痛，但不會對你造成嚴重傷害。
毛毛蟲和其他蟲子 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 saddleback caterpillar is the larva of a moth found in eastern North America and Mexico. It is green with a brown saddle-shaped marking on its back, and its spiny hairs can cause a painful rash. Gardeners who handle plants where it lives are most at risk of contact.1

It is most often found on ornamental plants and palms, where gardeners are most at risk of accidental contact. It is polyphagous, meaning it feeds on many plant species rather than just one.1

牠吃什麼？
The larvae feed on plants. In Florida and Alabama in the United States, they feed on palms such as the Manila palm (Adonidia merrillii). Later in life they feed on both sides of the leaf.1

怎麼認出牠

  • Primarily lime-green, with brown at both ends.1
  • A dark brown centre marking, outlined in white and black, that looks like a saddle.1
  • A pair of fleshy horns, called tentacles, at each end of the body, which are orange or black as the caterpillar grows.1
  • Tufts of spines along the body, with a row of orange spines along the sides.1
  • Some larvae have a false face at the rear, with two pale dots that look like large eyes.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 hairs and spines contain an irritating venom that is released when they touch skin or are broken. Contact causes a painful, swollen rash and sometimes nausea. Severe reactions are possible and can include migraines, breathing trouble related to asthma, anaphylactic shock (a dangerous allergic reaction) and bleeding. Symptoms can last from a few hours to a few days, depending on how sensitive a person is.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。

This caterpillar has one of the strongest stings of its kind. Gardeners are most at risk because the caterpillar is common on ornamental plants. Symptoms vary from mild to severe, and the sensitivity of the person affected makes a difference.1

好消息：醫生有藥（抗毒血清）或治療方法。1

牠害怕時會做什麼？

When threatened, the larva curls outwards so its spines are hard for a predator to avoid, and its bright colours warn of its toxicity.1

如果你碰到牠的毛

  • Remove the spines from the skin immediately using adhesive tape over the affected area, with a new piece of tape for each treatment, to stop the venom spreading. Ice packs, corticosteroids and antihistamines (taken orally or applied to the skin) have been reported to help relieve pain. Symptoms are relieved with prescribed medication on a case-by-case basis.1
  • 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

小知識

1

The false face on the rear end is thought to confuse predators, which may attack the wrong end.1

2

Its cocoon is made of silk mixed with its stinging spines, which protect the pupa during metamorphosis.1

3

Braconid wasps often lay their eggs inside these caterpillars, and the wasp larvae feed from the inside and later emerge through holes in the body.1

4

Like other slug caterpillars, it moves on suckers and mucus, which help it roll and stick to surfaces.1

5

The adult moth has no sting and lives about 10 days on average.1

6

The adult moth loses the caterpillar's bright colours and has velvety dark brown forewings and cream hindwings.1
