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

Apa kesan bisanya?

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

Berapa bahaya ia kepada manusia?

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

Apa yang ia buat apabila takut?

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

Fakta

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
