Sloth moth
Chrysaugine moths, such as Cryptoses spp., spend their lives as adults in the fur of sloths, particularly the three-toed species, except when the sloths descend to defecate and females fly to the sloth dung to oviposit. An imbalance in population sex ratios favouring males has been noticed and surmised as female moths not making it back to host sloths after ovipositing.
