Orthoporus dorsovittatus

Orthoporus dorsovittatus is a Millipede (Diplopoda) in the family Spirostreptidae. The species has come to some "popular acclaim" after it was reported that wedge-capped Capuchin monkeys (Cebus olivaceus) seek out this species of millipede and then intentionally rub the animal in their fur - sometimes sharing the millipede between a few monkeys - in order to coat themselves with the defensive secretion of the millipede, which contains benzoquinone-containing and supposedly acts as a repellent for mosquitoes. Such "anointing" behaviour in animals other than humans is relatively rare and usually of interest to researchers.
