The southern yellowjacket is a social wasp with black and yellow stripes and an orange queen. It lives in eastern North America and further south into Central America. Its nests are often in yards, parks and by roads, so people meet it often, and its stings are painful.1

Nests are usually in unnatural or disturbed places such as yards, parks, picnic tables and roadsides, and in wall voids. Some colonies are in pine forests or hardwood forests. Most nests are underground, though some are above ground or in walls. The species is common in urban areas.1

Zer jaten du?

It is predatory and mainly eats live insects, especially arthropods such as spiders and caterpillars. It also feeds on the flesh of dead prey. Adult workers bring food back to the larvae in the nest.1

Nola ezagutu

Black body with yellow striping over the whole body1
Clear wings and a hairless body1
About 1.3 cm long1
The queen is larger than the males and workers and is more orange in colour1
Has two stripes on its scuta1

Askotan honekin nahasten da: Its two stripes on the scuta are shared with V. sulphurea. The queen looks different from the workers and males, so check the colour and size of the wasp you see.1

Pozoi-ahalmena

Ziztadak

Pozoia ezten batetik ateratzen da.

Zer egiten du bere pozoiak?

Its stings are venomous, and the venom causes pain. Workers can sting several times in one attack.1

Zein arriskutsua da pertsonentzat?

Arriskua pertsonentzat: MingarriaBenetan min handia eman dezake, baina ia inoiz ez da larria.

The species is considered a pest because its nests are close to people and can be large. Close contact with people commonly leads to multiple, painful stings. Disturbing a nest can result in several stings.1

Zer egiten du beldurtzen denean?

Workers release alarm pheromones that signal the rest of the colony to attack whatever threatens the nest. Their stings are typically used in defence of the colony.1

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.

Datuak

Most southern yellowjackets are social parasites: they build their nests around the nests of another species.1

About 85% of colonies start when a queen takes over a small nest of the eastern yellowjacket, V. maculifrons, and only about 15% are founded independently.1

Some nests are very large. One of the biggest reported was in a pine tree and the dirt beneath it, and it had over 50 combs in the trunk alone.1

In Florida and other southern coastal areas, some nests survive the winter and last for several years.1

Workers and queens use pheromones to communicate, with alarm signals for attacks and a different pheromone that attracts males to the queen.1
