Wombat flies are tiny native Australian flies belonging to the tribe (a taxonomic classification between genus and family) Borboroidini. When a female enters oestrus she becomes active and aggressive. We present the first high-resolution carbon and oxygen isotope profiles of carbonate in modern wombat (genera Vombatus and Lasiorhinus) tooth enamel and demonstrate that the carbon isotope ratios (δ 13 C) clearly preserve seasonal changes in diet and local environmental conditions. Common Wombat’s distinguishing features are: large and naked nose; coarse thick coat; short, slightly rounded ears. Today the species has a discontinued and fragmented distribution. They have teeth like rodents. Similarly, in the vicinity of other domestic stock, wombats can get infected with leptospirosis which causes serious kidney damage.
