Beetles

The fauna of virgin Australia, abundant in exotic animals like kangaroos, platypuses, emus, cockatoos, absolutely did not know many species of animals widely distributed on other continents. Accustomed to dairy products, the British colonialists hastened to bring to the fat pastures of their new homeland of cows. And this almost led to disastrous consequences. Just in the meadow grasses of the Australian pastures did not live the natural orderlies - dung beetles. As a result, cow dung began to poison vegetation, bare barren soil was subjected to active erosion, which killed nearly a million hectares of fertile land.

And at the end of the 19th century, an unusual import article appeared in British foreign trade: the British government began to buy all kinds of dung beetles in large quantities in Europe and Asia. Of the 57 species imported to Australia, beetles caught on about 20. Dung beetles adapted to the new conditions and began their laborious and useful work in poisoned areas, which gradually began to come to life. That was one of the first "calls" that warned how dangerous even such a seemingly insignificant violation of ecological balance in nature.

Dung beetles have a length of 3 to 70 mm. The body is oval or round, yellowish, brown, yellow-brown, red-brown, purple, brown or black. Antennae 11-segment with 3-segment mace. In nature, there are over 600 species of dung from 68 genera.

It turns out that some dung beetles do not feed at all. Many species lead a secretive way of life, most of which live in their burrows. Adult beetles do not care about their larvae, they just leave the larvae eating in the burrow and leave it. The history of development in different species proceeds in different ways. Adult beetles burrow into vertical mink, which in depth can be from 15 to 200 cm, and also make larval cells under the cover of foliage, cow manure, horse litter. Mink of several species can be up to three meters deep. In some places there are species that live in semi-colonies. Most of the dung beetles are night inhabitants and are often attracted by the light of lamps or searchlights.
