Abstract
Two dung beetle assemblages from rainforest and open forest in the wet tropics of north-eastern Australia are described. The fauna was sampled using flight intercept traps, baited pitfall traps and light traps, with flight intercept traps being the most effective sampling technique. Dung beetle species were found to be highly habitat specific with a switch from rainforest to open forest assemblages occurring over tens of metres. The majority of the fauna was active at night. The most abundant species were attracted to a variety of food types but several species appeared to specialize on either dung or mushrooms.
