A study showed there were gaps in the network and so in a new species of dung beetle was introduced in Western Australia. The success of the project is reflected in the fact that there has reportedly been a 90 per cent reduction in the number of bush flies. The introduction of exotic dung beetles and their subsequent establishment in Australia is now history, and a very successful one at that.
However, it fell short in filling all the climatic areas with their vast variety of habitats. The National Museum of Australia acknowledges First Australians and recognises their continuous connection to country, community and culture. Defining Moments Dung beetles in Australia.

Dung Down Under The power of the dung beetle In our collection. The painting depicts beetles and birds. However, many dung beetles feed on a variety of things, including mushrooms, decomposing leaves and other rotting matter.
Adult dung beetles have mouth parts which are specially adapted to feed on liquefied material and can break down a dung pad very efficiently by burying the dung underground to use when breeding.
A pair of dung beetles a male and a female may work together, digging a nest to create a burrow beneath the dung pad. The dung is taken into the burrow in either a ball or an irregular mass. The female lays her eggs in the burrow. The eggs hatch into larvae, which feed on the dung surrounding it. The larvae will go through three skin changes to reach the non-feeding pupal stage.
Male larvae develop into major or minor males depending on how much dung is available to them during their larval phases. Some dung beetle larvae are able to survive unfavourable conditions, such as droughts, by stopping development and remaining inactive for several months. The pupae turn into adult dung beetles, which break out of the dung ball and dig their way to the surface.
The newly formed adults will fly to a new dung pad and the whole process starts over. Dung beetles serve a number of very important ecological functions. Pastures were in ruin and the native bush fly was flourishing in sloppy, wet cow dung.
Back in the s, our scientist George Bornemissza was the first person to put the biological link back in the chain. He brought in the first introduced dung beetle species as biological control agents. Fast forward to June and a new shipment of Moroccan dung beetles Gymnopleurus sturmi has arrived on Australian shores.
