Why are warning colours in animals so rare? Toxic insects display warning colours as protection from predators who learn to associate them with an unpleasant taste. Theoretically, there is no limit to the number of species that could show warning colours but only about 5% are estimated to have them. This presents a fundamental and unresolved biological problem - what limits warning colours? This project aims to address this significant biological question by testing three hypotheses predicting warning signal limitations. Projected outcomes are an improved understanding of the ecological niche of these colourful insects, which may inform conservation and biodiversity management and raise awareness of these flamboyant creatures..
