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

Que come?
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

Como recoñecelo

  • Primarily lime-green, with brown at both ends.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

Poder da pezoña

Pelos urticantes

Pelos ou cerdas pequeniñas rompen dentro da pel e pican.

Que fai a súa pezoña?

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

Que perigoso é para as persoas?

Perigo para as persoas: DolorosoPode doer moito, pero case nunca é grave.

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

Boas novas: os médicos teñen un medicamento (antiveleno) ou un tratamento para isto.1

Que fai cando ten medo?

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

Se lle tocas os pelos

  • 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
  • Para os pelos urticantes das eirugas: quítaos con cinta adhesiva e despois lava a pel. Non esfregues.
  • Para as mordeduras: lava e arrefría. Busca axuda médica se a persoa se sente mal ou sangra con facilidade.

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se lle tocas os pelos: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

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
