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

It lives in trees and shrubs, including pear, apple, maple and oak, and is a pest of fruit orchards and hardwood forests. People meet it when the caterpillars and their winter tents are on trees, and when shed hairs blow onto lawns, clothes and shoes.1

Hvad spiser det?
Caterpillars feed on the leaves of many kinds of trees and shrubs, a habit that is unusual for a single species. They feed in groups in the spring and summer and then overwinter in communal tents.1

Sådan genkender du det

  • 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

Forveksles ofte med: 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

Giftkraft

Brændehår

Bittesmå hår eller børster knækker af i huden og svier.

Hvad gør dets gift, når det bider eller stikker?

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

Hvor farligt er det for mennesker?

Fare for mennesker: SmertefuldDet kan gøre rigtig ondt, men det er næsten aldrig alvorligt.

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

Hvad gør det, når det er bange?

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

Hvis du rører ved dets hår

  • Ved brændehår fra larver: Løft dem af med tape, og vask derefter huden. Gnid ikke.
  • Ved bid: Vask og køl. Få lægehjælp, hvis personen har det dårligt eller let bløder.

Ring altid først til dit alarmnummer (112, 000, 911). Dette er generel førstehjælpsvejledning, ikke lægelig rådgivning. Grundlæggende førstehjælp

Pas på dig selv

  • Rør aldrig ved, fang eller dril et vildt dyr, heller ikke et lille et, og heller ikke hvis det ser ud til at sove eller være dødt.
  • Giv det plads. Hvis du møder et, så bliv rolig, træd langsomt tilbage, og lad det gå sin egen vej.
  • Hvis du rører ved dets hår: Bevar roen, hold dig i ro, ring til dit alarmnummer (112, 000, 911), eller kom hurtigt på hospitalet. Husk, hvordan det så ud, et billede hjælper.

Det er ikke ude efter dig. Det bruger sin gift til at fange føde eller beskytte sig selv, og det gemmer sig meget hellere. Mere om sikkerhed

Fakta

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

Myteknuser

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

Sandhed: 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
