The life cycle of the Dung Beetle. | |
![]() AMRC Review No. 80 The beetles feed on the bacteria in the liquid of the dung.
Good Dung and Bad Dung However, the gut bacteria of the grazing animal is altered by feeding grain (increased gut acidity), the heavy use of nitrogenous fertilisers, and by drought (fibrous grasses) so that the beetles are not attracted to dung from such feeds. Irrigated dairy farms are crucial for the survival of beetle colonies during dry summers. In particularly dry summers, G. spiniger emerges much earlier in the season (in January rather than normally following the first good rain in mid-February to March). In such dry years dung beetles have been observed to be attracted even to chook dung which they would normally leave alone. In Tasmania, we only have species that bury dung in tunnels; we have no dung ball rollers.
