The oak processionary is a moth whose caterpillars feed on oak leaves and can strip trees bare. The caterpillars travel in long, nose-to-tail lines, which is how they got their name. Their fine, hair-like bristles can irritate skin and breathing, so they matter a lot to people.1

Cara mengenalinya

  • Adult moths have a wingspan of 25 to 35 mm and are tan, brown and white, which makes them hard to see against oak bark.1
  • Caterpillars have very long, white hairs that contrast with shorter hairs.1
  • Caterpillars march in lines, often arrow-shaped, with a leader and rows of several caterpillars side by side.1
  • Nests are white and silk-like when new, and become discoloured and hard to see over time.1
  • Nests can be round, teardrop-shaped, bag-like or blanket-like, and can be found at any height on an oak tree.1

Sering tertukar dengan: Caterpillars of several other species may be mistaken for the oak processionary. Unlike other caterpillars, the oak processionary does not live on fences or walls, so it is mostly found in oak trees or on the ground beneath them in late spring and early summer.1

Kekuatan bisa

Bulu penyengat

Bulu atau rambut mungil patah di dalam kulit dan menyengat.

Apa efek bisanya?

The caterpillars' back bristles contain a urticating toxin called thaumetopoein, a protein that irritates the skin. Contact can cause a papular rash and itching, and the hairs can also cause eye inflammation (conjunctivitis). If the hairs are breathed in, they can cause sore throat (pharyngitis), breathing problems, asthma, or in rare cases anaphylaxis, a severe allergic reaction.1

Seberapa berbahaya bagi manusia?

Bahaya bagi manusia: MenyakitkanBisa sangat sakit, tetapi hampir tidak pernah serius.

The moths are an increasing nuisance to people as their range grows, and the hairs can cause a skin condition called epidemic caterpillar dermatitis. The hairs break off easily, float in the air, and can stay harmful for several seasons. Mowing a lawn can bring people into contact with them.1

Kabar baik: dokter punya obat (antibisa) atau pengobatan untuk ini.1

Apa yang dilakukannya saat takut?

The caterpillars defend themselves with thousands of pointed, easily broken bristles on their backs that float in the air and irritate the skin.1
