Bull ants marching up a tree

Bull ants - from somewhere around Exmouth, Western Australia..

 

According to the Australian Museum, they are "large, alert ants that can grow up to 40 mm (more than one and a half inches [1.5748 inches]), with characteristic large eyes, long, slender mandibles (jaws) and a potent venom-loaded sting. I can attest to the sting bit.
