Wild wedge-capped capuchin monkeys (Cebus olivaceus) self-anoint with millipedes (Orthoporus dorsovittatus).Chemical analysis revealed these millipedes secrete two benzoquinones, compounds known to be potently repellent to insects [6] and the secretions are thought to provide protection against insects, particularly mosquitoes (and the bot flies they transmit) during the rainy season.
