Solifugae many species also are used for stridulation. Unlike scorpions, solifugids do not have a third tagma that forms a "tail". Most species of Solifugae live in dry climates and feed opportunistically on ground-dwelling arthropods and other small animals. The largest species grow to a length of , including legs.

Solifugae are moderately small to large arachnids (a few millimeters to several centimeters in body length), with the larger species reaching in length, including legs. In practice, the respective
Arthropods associated with sloths fur of the sloth to lay eggs in the sloth droppings when the sloth descends, once a week, to the forest floor to defecate.

Lepidopterans belonging to the coprophagous guild that are specialised to live around sloths include: Arthropods associated with sloths A large number of arthropods are associated with sloths.
