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

Apa kesan bisanya?

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

Berapa bahaya ia kepada manusia?

Bahaya kepada manusia: MenyakitkanIa boleh jadi sangat sakit, tetapi hampir tidak pernah serius.

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

Berita baik: doktor ada ubat (antibisa) atau rawatan untuk ini.1

Apa yang ia buat apabila takut?

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

Jika kamu menyentuh bulunya

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
Untuk bulu ulat yang menyengat: angkat bulu itu dengan pita pelekat, kemudian basuh kulit. Jangan gosok.
Untuk gigitan: basuh dan sejukkan. Dapatkan bantuan perubatan jika orang itu berasa tidak sihat atau mudah berdarah.

berguna untuk diketahui

Fakta

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
