They learnt that the spurned males used their hook-like antennae to latch on to the females and mate. Professor Locke Rowe, University of Toronto, said that the antennae have developed so that they match the shape of the female's head, fitting like a harness around the female's eyes. Rowe said, “We weren't looking at simple modifications, but a sensory device (the antennae) that had evolved in males into a spectacularly modified grasping device - large, muscular, and fitted with hooks and spikes exquisitely adapted for grasping - a long way from an insect ‘feeler'. The study gives us new insight into the evolution of novelty, and novelty is one of the most spectacular outcomes of the evolutionary process."
