Animal senses and signals are amazingly diverse,and the major modalities by which animals acquire sensory input from their envi-ronments are sound,light,vibration,and chemical signals.Insects mainly rely on visual,nociceptive,and olfactory cues to discriminate between rewards and risks.It has been shown that the visual and ol-factory cues of predators substantially affect the adult phenotype in Drosophila melanogaster(Krams et al.2016),a prominent animal model for biological research.A recent study has found that fruit flies can rely solely on vision in predator detection(de la Flor et al.2017).
