Examples may be found in the arthropods associated with sloths. Coprophagous sloth moths, such as Bradipodicola hahneli and Cryptoses choloepi, are unusual in that they exclusively inhabit the fur of sloths, mammals found in central and South America. The sloth provides transport for the moths, the females of which oviposit in the droppings of sloths, which the larvae feed on, and the newly hatched moths move into the forest canopy in search of a new sloth host. Varroa mite life cycle has two stages (Fig. 1). During the phoretic stage, mites ride on adult workers or drones, at the same time feeding on blood (hemolymph) from bees, usually from the inter-segmental membrane on the abdomen. The phoretic stage lasts about 5-11 days when there is brood in the colony. Of … See more There are two methods for studying mite reproduction.
