A Remarkable Beetle Some of the most remarkable beetles are the dung beetles which spend almost their whole lives eating and breeding in dung . More than 4 000 species of these remarkable creatures have evolved and adapted to the world s different climates and the dung of its many animals. Australia s native dung beetles are scrub and woodland dwellers specialising in coarse marsupial droppings and avoiding the soft cattle dung in which bush flies and buffalo flies breed. In the early 1960s George Bornemissza then a scientist at the Australian Government s premier research organisation the Commonwealth Scientific and Industrial Research Organisation CSIRO suggested that dung beetles should be introduced to Australia to control dung-breeding flies. Between 1968 and 1982 the CSIRO imported insects from about 50 different species of dung beetle from Asia Europe and Africa aiming to match them to different climatic zones in Australia. Of the 26 species that are known to have become successfully integrated into the local environment only one an African species released in northern Australia has reached its natural boundary. Introducing dung beetles into a pasture is a simple process approximately 1 500 beetles are released a handful at a time into fresh cow pats 2 in the cow pasture. The beetles immediately disappear beneath the pats digging and tunneling and if they successfully adapt to their new environment soon become a permanent self-sustaining part of the local ecology. In time they multiply and within three or four years the benefits to the pasture are obvious. Dung beetles work from the inside of the pat so they are sheltered from predators such as birds and foxes. Most species burrow into the soil and bury dung in tunnels directly underneath the pats which are hollowed out from within. Some large species originating from France .
