European Wasps / Vespula germanica
In Australia, the European wasp (Vespula germanica) is a well-established pest. This non-native wasp was discovered in Australia for the first time in Tasmania in 1959. They were also well-known in Victoria, South Australia, New South Wales, and Western Australia by 1978.
European wasps are large with bright yellow and black banded abdomens and two black spots on each yellow band.
They have two pairs of clear wings, the first of which is larger.
They fly with their legs close to the body and have black antennae.
Danger to humans:
When their nests are disturbed, European wasps become more aggressive than bees.
Wasps, unlike bees, can sting multiple times and do not die after stinging.
The sting causes a burning sensation as well as swelling. A more severe systemic reaction may occur if there are multiple stings.
Wasp, bee, and ant stings can cause an allergic reaction (anaphylaxis) in some people, but this is uncommon.
There is an effective treatment available, which entails known bee/ant/wasp sting allergy sufferers carrying a special kit when outdoors.
