Madagascar’s red-fronted lemurs (Eulemur rufifrons) eat millipedes to both prevent and cure infections caused by some parasites, according to a study published in Primates yesterday (July 30). 

“Eating millipede secretions may be a way of self-medication,” Louise Peckre, a doctoral student at the Leibniz Institute for Primate Research in Germany, says in a statement.  

Besides eating the creatures, the primates also applied munched-up millipedes to the areas surrounding their genitalia and anuses and to their tails. Peckre and colleagues  believe the millipedes produce a compound called benzoquinone, known to repel mosquitoes, which may help the lemurs keep parasites out of their gut and away from their anuses.
