The eggs of certain species of insects, many of which are of great economic importance, absorb water from the external environment. Water uptake in these insects occurs in a definite stage in embryonic development. Previous studies on the egg or the house cricket, Acheta domesticus (L.), have shown that contact water is necessary for the development of the egg. The stage of embryonic development at which water absorption occurs, and the mechanism or absorption, however, have not been studied. In the present investigation, water uptake by the egg is studied, the stage of embryonic development at which this uptake occurs is determined, and the mechanism or absorption is analyzed.
