Müllerian mimicry between chemically defended species arises from selection exerted by predators in which individuals benefit from higher survival when they share the same warning signal. However, despite sharing warning signals, co-mimetic species harbour a diversity of toxins at a range of different concentrations. This variation may affect the rate of predator avoidance learning and therefore the dynamics of mimicry. Here, to understand the nature of mimetic relationships in natural communities of butterflies and moths, we compared protection against predators induced by chemical defences of 13 lepidopteran species belonging to six mimicry complexes. Protection was estimated by quantifying the extent of avoidance learning, using domestic chicks, Gallus... |
