The article studied the thermodynamic processes that occur during the drying of the cocoon, and found that the main amount of moisture (humidity 200-280%) is in the chrysalis, and 160-180% - in the cocoon. It was revealed that the main resistance to drying falls on the cocoon shell, pupae without shell dry 2.5 times faster. Relations describing the mass conduction fluxes for cocoon layers are given, and a differential equation for air permeability under pulsating pressure is derived.
