There are many species of Australian mud wasp, which belong to the Families Specidae and Vespidae. While varying in colour and size, they are often black with yellow or orange bands. Mud wasps are solitary insects, feeding on nectar and drinking water.

Mud wasps can be seen near the edges of puddles or streams drinking or gathering mud for their nests.

Potter Wasp

A large and colourful Potter Wasp (Abispa ephippium) collects mud from my eroded driveway. Potter Wasps live in open habitats and gardens, and are found across much of mainland Australia.

Nests are constructed by single female wasps. Some species build their nests in cavities such as in trees or old machinery (even taps), while others attached their mud nests to tree trucks, rocks, or in Rob’s case, buildings.

A temporary entrance funnel (seen here) is built while the cells are being filled.

The female catches a spider or insect (depending on species of wasp), then stings and paralyses it. The hapless insect is carried back to the nest, whe an egg is laid on it and the nest sealed. When the wasp grub hatches it consumes the food provided and pupates in the cell. The emerging adult wasp then chews its way out of the cell.

Mud wasps are native animals. They are not pests and rarely sting, as they are not usually aggressive to humans.

    Hello Rob,

    Many housewives wouldn't like wasp nests on their walls, but I am delighted to have the potterer return to the same nest for the third year in a row, and even more thrilled to see her on your website.

    You are quite correct she is not in the least bit viscous, elegantly swerving between our tea cups and saving me having to clean up cobwebs on the verandah by entombing all the young spiders.

    We were not so happy with nature on Saturday, the girls went out to get eggs for breakfast only to find a carpet snake strangling their bantam hen. He did apologise and spat her out due to all the crying and screaming, but it was too late. A neighbour told me that her father took an axe to one between its bumps and resuscitated all the kittens it had eaten!!

    Cheers, Catherine
