They function primarily in osmoregulation and the removal of nitrogenous waste products from the hemolymph of insects, conserving water in the process.
They dangle in the fluid of the body cavity and open into the digestive tract at the juncture of the midgut and hindgut. Certain waste solutes are pumped across their membranes and transported into the intestinal tract and then excreted through the insect's anus.
