The brown-tail moth is a moth whose caterpillars are covered in tiny irritating hairs. It is native to Europe, neighbouring parts of Asia and the north coast of Africa. Its hairs can cause a very itchy rash, so it matters to anyone who works or plays near trees it feeds on.1

Como recoñecelo

  • Adults have pure white upper wings and a hairy white body with a tuft of brown hair at the tip of the tail end.1
  • Adults have a wingspan of 36 to 42 millimetres.1
  • Caterpillars are very hairy, brown with white markings, and have two prominent red spots toward the tail end.1
  • In late autumn and winter, silken tents hang on branch tips, which are a sign that the caterpillars are present.1

Adoita confundirse con: Euproctis similis, also native to Europe, is similar as an adult but the female has a yellow tail tuft. Hyphantria cunea, native to North America, is similar too, but it lacks the coloured tail tuft.1

Poder da pezoña

Pelos urticantes

Pelos ou cerdas pequeniñas rompen dentro da pel e pican.

Que fai a súa pezoña?

The hairs are not venom injected by a bite or sting. They are toxic and irritating to skin. Barbed hairs lodge in the skin and cause physical irritation, and chemicals in the hairs also irritate it. If inhaled, the hairs can cause breathing difficulties similar to asthma. The toxins stay active for up to three years after the hairs are shed.1

Que perigoso é para as persoas?

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

Contact with the hairs causes a very itchy rash that can last for weeks. Doctors reported rashes worse than poison ivy rash in the early 1900s. Breathing difficulties can occur if the hairs are inhaled.1

Que fai cando ten medo?

Its hairs protect the caterpillars from predators, and the caterpillars use some hairs in their cocoons.1

Se lle tocas os pelos

  • Para os pelos urticantes das eirugas: quítaos con cinta adhesiva e despois lava a pel. Non esfregues.

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 hairs of the caterpillars can cause a rash even when no one touches a caterpillar, because shed hairs can blow in the wind.1

2

Brown-tail moths were described in outbreaks in Paris, London and Berlin as far back as the 1500s, when they stripped trees of leaves.1

3

The species spends about nine months of its year as caterpillars, which is unusually long for a moth.1

4

Caterpillars spend the winter together in silken tents built at branch tips, rather than spreading out.1

5

A parasitic fly introduced to North America in 1906 to control spongy moths also strongly affected brown-tail moths.1

Desmontamitos

Mito: You can only get the rash by touching the caterpillars.

Verdade: Hairs are shed and can become windblown, and they can be carried indoors on clothing and shoes, so a rash can occur without direct contact with the caterpillars.1
