Özet: Four coleopteran species of Cantharis livida Linnaeus, 1758 (Cantharidae), Gastrophysa polygoni Linnaeus, 1758 (Chrysomelidae), Malachius bipustulatus Linnaeus, 1758 (Melyridae) and Certallum ebulinum (Linnaeus, 1767) (Cerambycidae) from different regions of Iran exhibited an obvious resemblance to the predominant meloid species occurring where they were collected. Tiny amounts of cantharidin- far below the average content for meloids was detected in them using GC-MS analysis. Because of the evident similarity (approximate size, general colouration, elytral pattern, habitat and seasonal activity) between each of these cantharidin-bearing mimics and their meloid models, it is assumed that a Müllerian mimicry exists reciprocally in which some non-producer beetles obtain cantharidin from external sources to be chemically protected against their natural enemies and enhance their natural fitness
