Ranitomeya poison frogs in the Peruvian Amazon are a rare example of Müllerian mimicry in vertebrates. These frogs also prefer to court same-coloured mimics. This suggests that divergence in mimicry plays a role in reproductive isolation.

Color pattern mimicry has long been held up as a powerful example of natural selection. A recent study supports the theory by describing Müllerian mimicry rings in Appalachian millipedes that are analogous to those observed in tropical butterflies.

Can undefended mimics survive outside the range of their noxious models? Two recent studies on Batesian mimicry suggest they can, but alternative survival strategies and morphologies are then favoured.

Eye gaze and behavioral mimicry are important foundations of social interaction. Inspired by recent studies on eye-gaze mediated spontaneous behavioral mimicry of gestures, we studied the effect of eye gaze direction on vocal mimicry. Participants were instructed to repeat digits spoken by a virtual agent with a direct or averted eye gaze. As a measure of imitation, the vocal pitch was recorded...
