The females of the genus are well known for their painful sting, which is where many gain their common name, Cow Killer. The female is wingless and often resemble large ants while the males still retain their wings. The larvae are external parasites to various types of hymenoptera. When disturbed, Dasymutilla makes a high-pitched squeaking sound identical to that of the Pogonomyrmex (Harvester ant). Many species in the genus are Müllerian mimics of each other; together they form several mimicry rings in one of the largest known mimicry complexes. The effect is to warn off predators by shared aposematic coloration without requiring inexperienced predators to taste and be stung by members of each species separately.[1][2] Selected Species
