Common paper wasps
Polistes humilis or common paper wasps are generally slender with long thin wings.
They are 10-15 millimetres long, tan in colour with darker bands and some yellow on the face.
Other species of paper wasps are larger or smaller and differently coloured.
Paper wasps make nests of grey papery wood fibre material.
The nests are cone-shaped, becoming round as more cells are added.
Nests are a maximum diameter of 10-12 centimetres, with numerous hexagonal cells underneath, some with white caps.
Nests are exposed and suspended by a short stalk under an overhang, often on a pergola, the eaves of a roof or in a shrub or tree.
Wasps cluster on the nest or forage in the garden and around buildings.
Paper wasps are found across mainland southern Australia including:
New South Wales
the Australian Capital Territory
southern Western Australia.
Polistes humilis are a native wasp species, but other paper wasp species are introduced.
Paper wasps are a social wasp consisting of small colonies of 12-20 individuals.
Adult wasps feed on nectar and make ‘paper’ nests by mixing saliva and wood fibres.
Nests are a nursery where larvae are kept one to each cell.
The larvae are fed on chewed-up caterpillars caught by the adults.
The cells are then capped and the larvae pupate. Most paper wasps die in autumn or winter, while some hibernate to start new nests next season.
