Cantharidin is an odorless, colorless fatty substance of the terpenoid class, which is secreted by many species of blister beetles. Its main current use in pharmacology is treating molluscum contagiosum and warts topically. It is a burn agent, poisonous in large doses. It has been historically used as an aphrodisiac (in preparations sold under the name "Spanish fly"). In its natural form, cantharidin is secreted by the male blister beetle, and given to the female as a copulatory gift during mating. Afterwards, the female beetle covers her eggs with it as a defense against predators.
