Mud Dauber or Mud Wasps

There are many different species of Australian mud wasps in the Families Vespidae and Sphecidae. They vary in size and colour but are often all black or black with orange or yellow bands or markings. They build nests of mud or 'clay'.
Mud wasps are found all over Australia and in all terrestrial habitats.
They are solitary insects and the nest is constructed by a single female wasp. Some species attach nests to rock faces, tree trunks or buildings.
Others build inside cavities, such as holes in tree trunks or machinery and in infrequently used taps and pipes or the handles of tools left outside.
