Coleoptera, Meloidae. Ed. Calderini, Bologna, 541 pp. ISBN 88-7019-523-6 En Argentina reciben el nombre vulgar de bicho moro.
Las larvas se alimentan de huevos de saltamontes; algunas especies se alimentan de huevos de otros Epicauta. Los adultos se alimentan de plantas.Kerr, J. T. and L. Packer. (1999). The environmental basis of North American species richness patterns among Epicauta (Coleoptera: Meloidae). Biodiversity & Conservation 8(5), 617-28. Incluye algunas especies que son consideradas plagas para la agricultura. Segregan como defensa un líquido vesicante, la cantaridina, que produce ampollas en la piel por contacto directo y que hasta puede causar la muerte de animales como caballos si comen estos insectos.DiFonzo, C.
