According to animal signalling theory, various mechanisms can maintain signal honesty in the face of deception. Conventional signals are usually cheap to produce but socially imposed costs, often taking the form of aggression from conspecifics, can enforce their honesty. While our understanding of signal evolution and honesty has much improved for some pigment-based colour signals, the mechanisms maintaining the honesty of structural colour signals, such as ultraviolet (UV), remain elusive. Here, we used the common lizard Zootoca vivipara to test whether or not the honesty of UV signals displayed on male throats is under social control. To do so, we staged dyadic agonistic interactions between non-manipulated focal males and opponents of ei...
