What Wasps Are in NZ?
WouterThroughout New Zealand there are many wasps, many of which are native. There are also several introduced species. These non-native wasps can cause a nuisance and damage the native ecosystems. They are also dangerous to humans. They can sting and cause allergic reactions.
Generally, there are four species of pest wasps in New Zealand. The first one is the common wasp. It is native to parts of Asia. The common wasp is a social wasp, meaning all members of the colony help raise young. Its nest is a brown, hexagonal structure. The nests can be very difficult to locate.
The second species is the German wasp. This wasp was first discovered in the 1940s. It has a black and yellow body, a long tail and triangular markings. The nest is usually underground, but it can be found on the ground. It has no natural predators. It can grow quite large if the colony survives winter.
There are also Asian paper wasps. This species is larger than the Australian paper wasp and has similar characteristics. It also builds nests under branches and leaves. It is also similar in behaviour and temperament to the Australian paper wasp. It can sometimes be confused with the German wasp.
There are also two other species of paper wasp in New Zealand. The Australian paper wasp is found in both urban and rural areas. The nests are made of plant fibres.
These wasps are a problem in orchards, vineyards, and other areas. They eat live insects, including bees, butterflies, and caterpillars. The larvae secrete honeydew, a sugary droplet. This honeydew provides energy-rich food for native animals.
