The bald-faced hornet is a wasp with a striking black and white body and a white face. It builds large, hanging paper nests in trees and bushes across North America. Its workers will defend the nest by stinging repeatedly, so it is important to keep well away from its nests.1

Leef in

North America, including Canada, the Rocky Mountains, the western coast of the US and most of the eastern US. Most common in the Southeastern US.1

Noord-Amerika

Tuis

It lives in forested areas and in vegetation in towns and cities. Nests are usually in trees and bushes, but sometimes under rock overhangs or on the sides of buildings, from 0.3 m to 20 m above the ground. People meet it when they walk too close to a nest or when a nest is built near homes.1

Lengte

Topspoed

Wat eet dit?

Adults hunt flies, caterpillars, spiders and other insects, which they chew up and feed to the larvae. They also drink flower nectar, eat fruit such as apples, and have been known to scavenge raw meat.1

Hoe om dit te herken

Black and white colouring, unlike other yellowjackets of its genus, which are mostly black and yellow1
A white or "bald" face1
Three white stripes at the end of the body1
Adults average about 19 mm long, larger than other Dolichovespula species1
A large, egg-shaped, grey paper nest that hangs from trees or bushes, up to 58 cm long1

Word dikwels verwar met: Other Dolichovespula wasps are mostly black and yellow. The bald-faced hornet's black and white colouring and white face set it apart. It is not one of the true hornets, which belong to the genus Vespa.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

Workers can squirt venom from the stinger into the eyes of animals that intrude on the nest. The venom makes the eyes water immediately and causes temporary blindness.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

It is aggressive when defending its nest. Workers sting repeatedly, and colonies can have 400 to 700 workers. The risk is highest when people walk too close to a nest or when a nest is built near homes.1

Wat doen dit as dit bang is?

Workers defend the nest by stinging repeatedly and can squirt venom into the eyes of intruders.1

As dit steek

Skraap 'n byangel uit en koel die plek af.
As die persoon sukkel om asem te haal, die gesig of keel swel, of hy voel flou, is dit 'n allergiese noodgeval: bel jou noodnommer en gebruik sy adrenalienpen (outo-inspuiter) as hy een het.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

It can spray venom from its stinger into the eyes of nest intruders, causing temporary blindness.1

Its colony can have 400 to 700 workers, the largest recorded colony size in its genus, Dolichovespula.1

Female bee moths can lay eggs in its nests, and the hatched larvae feed on the eggs, larvae and pupae inside, sometimes destroying large parts of the nest.1

Its nests are made from chewed wood fibres mixed with saliva, which dries into a papery structure.1

A colony lasts about 4 months in Washington, from mid-May to mid-September. Colonies in lower latitudes last longer.1

Mite-breker

Mite: It is a true hornet.

Waarheid: It is a yellowjacket wasp. True hornets belong to the genus Vespa.1
