Step 1: Ion and water balance

Any species' ability to regulate water and ion balance depends on various hormonal factors, each affecting a different section of the excretory system or even a particular cell type within an organ. 
The volume of the hemolymph, the ionic makeup of the hemolymph, and the removal of metabolic waste products and toxins from the hemolymph are only a few of the associated factors that hormones control in insects.

Water balance can be modified by adjusting the rate of generation and/or composition of primary urine as well as the activity of the mechanisms that modify the primary urine
