How to identify European wasps

Page last updated: Wednesday, 15 May 2019 - 12:46pm

European wasps are declared pests in Western Australia and must be reported. Learn about European wasp distinguishing features and behaviours.

Suspect European wasp SIGHTINGS MUST BE REPORTED to the Department of Primary Industries and Regional Development.

Every year, fertilised European wasp queens are accidentally transported into our state in freight, cargo and vehicles from Eastern Australia. They must be detected and erradicated if we are to remain free of this pest.

Look for these distinctive characteristics

The European wasp has distinct behaviours among wasp species and other insects in Western Australia, which make it easier to identify.

 Did you know that...

  • European wasps are opportunistic predators and scavengers, eating dead animals, live insects, fruits, processed human and pet food (particularly meat and fish based food) and garbage. They are also attracted to sugars found in fruit and drinks.
  • European wasps make numerous trips between the location of the food source and the nest.

Similar looking insects

Because of their yellow and black stripes, several wasps, bees and flies can be mistaken for European wasps.

Native flower wasps (Families Tiphiidae and Scoliidae) are much larger. These harmless solitary wasps are beneficial pollinators. Although solitary they only come together during the mating season.

Yellow paper wasps are bright yellow and black. Paper wasps differ being slightly longer and thinner (more wasp-like) and have orange-brown antennae. Unlike European wasps, paper wasps hover with their back legs hanging down.

Honey bees are about the same size as European wasps, but have black legs, are hairier and are dull brown-orange in colour, as opposed to bright yellow and black.

Native Bembix wasps are smaller than European wasps and their antennae are shorter and thinner and their eyes larger. In a lot of Bembix species, the eyes are a yellow-green and the body colour is closer to a lime-green yellow.

Hover flies are smaller than European wasps and they 'hover' when flying. Their antennae aren’t easily noticeable (very short and stubby) and their large eyes meet together. They have one pair of obvious wings as opposed to two pairs of the European wasp (large pair and short pair).

European wasp or yellow paper wasp?

Yellow paper wasps are easy to confuse with European wasps. They are very common and widespread in WA and are frequently seen nesting in guttering, under fence capping or attached to bushes. Paper wasps are often seen visiting flowers, ponds or water taps. Look for their distictive papery honeycomb nest, or note the colour of the antennae and the position of the legs when they fly.

Differences between European wasps and paper wasps

 

European wasp

Paper wasp

Size

Workers: about 15mm long (size of a bee)
Queens: larger (not usually seen)

15–19mm long (longer than a bee)

Body shape

Stout body like a bee

Longer and thinner than a bee. Narrow waist

Colour

Bright yellow and black

Antennae (feelers)

All black (see picture above)

Yellow-orange (see picture above)

Flying

Legs held close to body during flight. Fly very quickly, generally do not hover

Back legs dangle down during flight. Often seen hovering around bushes, over lawns and around water sources

Food European wasps are scavengers feeding from pet food, meat or vegetable scraps, meat products, fish or dead insects Paper wasps feed on insects including caterpillars, flies, beetle larvae and nectar

Nests

Rarely seen

Often seen. Usually above ground

Location

Usually below ground with the entrance appearing as a hole in the ground. On rare occasions they may be found in a roof or wall cavity. It will have a busy entrance hole with many wasps entering and exiting per minute

Under fence capping or roof tiles, also under eaves and in dense shrubs. Sometimes in hollow steel piping and guttering

Size

Large. Growing in summer to be the size of a basketball or bigger

Golf ball to crumpet sized. Rarely as big as a dinner plate

Shape

Round or football shaped with an outer covering of insulating material that looks like grey paper mache or egg carton material

Single flat layer of papery honeycomb cells. Grey-brown in colour, often with some white-capped cells

Note REPORT - Do Not Treat Follow paper wasp control instructions
