Adenotrophic viviparity
From Wikipedia, the free encyclopedia
Adenotrophic viviparity
Name means "gland fed, live birth".This is the reproductive mode of many insects such as tsetse flies, gnats, moths, fleas, and mosquitos.
Eggs, with a chorion, are retained within the female's body and are nourished through "milk glands" until the developed larvae are ready to pupate. The larvae are then 'larviposited' and immediately pupate. This is one way insects avoid predation during their most vulnerable life stage.
