蜇毛吃：植物

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

在陆地上, 粗略估计

它吃什么？

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

怎样认出它

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

毒液之力

蜇毛

细小的毛或刚毛会断在皮肤里并刺痛。

它的毒液会造成什么？

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

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

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：医生有药（抗毒血清）或治疗方法。1

它害怕时会做什么？

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

如果你碰到它的毛

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

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果你碰到了它的毛：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

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

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

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

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

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

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