Versatile aggressive mimicry of cicadas by an Australian predatory katydid.

<h4>Background</h4>In aggressive mimicry, a predator or parasite imitates a signal of another species in order to exploit the recipient of the signal. Some of the most remarkable examples of aggressive mimicry involve exploitation of a complex signal-response system by an unrelated preda...
