Editing Diapause (section)

===Preparation===
The preparation phase usually follows the induction phase, though insects may go directly from induction to initiation without a preparation phase.<ref name="Kostal" /> During this phase, insects accumulate and store molecules such as [[lipids]], [[proteins]], and [[carbohydrates]]. These molecules are used to maintain the insect throughout diapause and to provide fuel for development following diapause termination. Composition of the [[cuticle]] may be altered by changing [[hydrocarbon]] composition and by adding [[lipids]] to reduce water loss, making the organism resistant to desiccation.<ref>{{cite journal |last1= HEGDEKAR |first1= B.
