A 'metaphising' dung beetle.
You may have seen the film Microcosmos, produced in 1996 by the French biologists Claude Nuridsany and Marie Perrenou. It does not star humans, but much smaller creatures, mostly insects. The filmmakers’ magnifying camera transposes the viewer into the world of these organisms. For me, Microcosmos is not an ordinary naturalist documentary; it is an exercise in metaphysics. One sequence in the f...
متن کاملFrom coprophagy to predation: a dung beetle that kills millipedes.
The dung beetle subfamily Scarabaeinae is a cosmopolitan group of insects that feed primarily on dung. We describe the first case of an obligate predatory dung beetle and contrast its behaviour and morphology with those of its coprophagous sympatric congeners. Deltochilum valgum Burmeister killed and consumed millipedes in lowland rainforest in Peru. Ancestral ball-rolling behaviour shared by o...
متن کاملRespiratory airflow in a wingless dung beetle.
The sealed subelytral cavity of many flightless beetle species is widely acknowledged to be an adaptation to water saving in arid-habitat species. However, this hypothesis relies on the acceptance of two largely untested assumptions: (i) that the movement of respiratory gases is unidirectional from anterior to posterior and (ii) that the coordinated action of the spiracles directs this flow. We...
متن کاملThe Dung Beetle Dance: An Orientation Behaviour?
An interesting feature of dung beetle behaviour is that once they have formed a piece of dung into a ball, they roll it along a straight path away from the dung pile. This straight-line orientation ensures that the beetles depart along the most direct route, guaranteeing that they will not return to the intense competition (from other beetles) that occurs near the dung pile. Before rolling a ne...
