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

बसोबास

Central and southern Europe, occasionally as far north as Sweden; now established in the UK and Belgium1

गृहपृष्ठ

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

लम्बाइ

यसले के खान्छ?

Caterpillars eat oak leaves, feeding in the tree crowns at night and returning to their nests. They also eat the leaves of hazel, hornbeam, sweet chestnut, birch and beech, though oak is preferred.1

यसलाई कसरी चिन्ने

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

प्रायः यससँग झुक्किइन्छ: 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

विष शक्ति

डस्ने रौँ

साना रौँ वा झुसहरू छालामा भाँचिएर डस्छन्।

टोक्दा वा डस्दा यसको विषले के गर्छ?

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

यो मानिसका लागि कति खतरनाक छ?

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

खुसीको खबर: यसका लागि डाक्टरहरूसँग औषधि (एन्टिभेनम) वा उपचार छ।1

डराउँदा यसले के गर्छ?

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

तिमीले यसको रौँ छोयौ भने

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
