Mylabris phalerata, Meloidae family of Coleoptera, has been known since antiquity to produce a potent toxic defensive agent, known as cantharidin (exo,exo-2,3-dimethyl-7-oxabicyclo [2.2.1] heptane-2,3- dicarboxylic anhydride), but well-known as Spanish Fly. In the past, Cantharidin has used as anticancer, herbicidal, pesticide and treatment of hepatic carcinoma and molluscum contagiosum activities.
