The sloth moth is a generic term used to refer to coprophagous moths which have evolved to exclusively inhabit the fur of sloths and to use sloth dung as a substrate for the early stages of reproduction. Adult female moths leave the fur of the sloth to lay eggs in the sloth droppings when the sloth descends, once a week, to the forest floor to defecate. The larvae live in the dung and newly emerged moths later fly from the dung pile into the forest canopy to find a host sloth. Sloth moths are considered to get nutrients from the secretions of the sloths’ skin and/or the algae present on the fur as well as protection from avian predators. Some three-toed sloths have been recorded carrying more than 120 moths in the fur of an individual sloth. Two-toed sloths are recorded as harbouring lower populations. Several different moth species may coexist on the same animal. (Wikipedia)
