Behaviour: Amphibians and Reptiles

Javier Aznar González de Rueda, Spain

The gladiator versus the beetle

Javier was taking pictures of the insects attracted to the lights of a lodge when his friend pointed out this tree frog battling a weevil. Javier framed his shot, the frog’s gold-flecked eyes echoed by the glow through the patterned glass. Two photos later, the weevil escaped and the frog narrowly avoided choking.

The Rosenberg’s gladiator treefrog is no stranger to aggression. Males must provide a nest to secure a mate and the ensuing territory disputes can be lethal. But their food doesn’t usually put up as much of a fight. Built like a tiny tank, this weevil is gripping the frog’s tongue as it would a leaf.
