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

Oak forests and oak trees, where the caterpillars feed and build silk nests on trunks and branches. People can meet them in oak woodland, on the ground under oaks, and in gardens and parks with oak trees. Their hairs can also reach lawns and garden ponds.1

Paano ito makikilala

  • 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

Madalas mapagkamalang: 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

Lakas ng kamandag

Nanunusok na balahibo

Maliliit na balahibo o buhok ang nababali sa balat at nanunusok.

Ano ang epekto ng kamandag nito?

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

Gaano ito kapanganib sa tao?

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

Magandang balita: may gamot (antivenom) o gamutan ang mga doktor para dito.1

Ano ang ginagawa nito kapag natatakot?

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

Kung mahawakan mo ang mga balahibo nito

  • The skin irritation and itching can be largely relieved by cetirizine-based antihistamine tablets. Anyone with breathing problems or a severe reaction needs urgent medical help.1
  • Para sa nanunusok na balahibo ng higad: alisin ang mga ito gamit ang sticky tape, pagkatapos ay hugasan ang balat. Huwag kuskusin.
  • Para sa kagat: hugasan at palamigin. Kumuha ng tulong medikal kung masama ang pakiramdam ng tao o madali siyang dumugo.

Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas

Mag-ingat

  • Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
  • Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
  • Kung mahawakan mo ang mga balahibo nito: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat
