. Final instar larvae of the ectoparasitoid Nasonia vitripennis overwinter in diapause within the puparium of the host fly. Wasp larvae that are in diapause have a different set of water relations than larvae that are not in diapause. Diapausing larvae contain less water, lose water at a lower rate, and have the capacity to absorb water vapour. Water conservation in larvae of N. vitripennis is also enhanced considerably by the puparium of its fly host.
