Abstract
Elaborate antipredator traits often evolve as signals directed toward multiple predator types. These elaborations can be paired with complex gestures that act redundantly or target different predator sensory systems, forming layered defenses. Yet, the context-dependent deployment of such signals remains poorly understood, particularly in non-model insect groups. Here, we investigate the role of the highly elaborate hind-leg “flags” of the matador bug (Bitta alipes, Hemiptera: Coreidae). These insects perform conspicuous flag-waving displays, yet the function of these striking traits has received little empirical attention. We perform experiments with bird and arthropod predators and uncover complex antipredator strategies. We find no evidence for social or sexual signaling with flags, but show that these traits function as effective signals against multiple predator types. Chemical assays reveal cyanide assimilation, consistent with an aposematic function. Together, our results suggest matador bugs selectively deploy conspicuous displays based on predator identity, highlighting how elaborate traits in a non-model insect functions within layered, predator-specific signaling systems.
