Some female flies that give birth to well- developed larvae rather than eggs secrete nourishment for their offspring prior to deposition from a gland called a milk gland. Viviparous insects display such glands, producing little or no yolk, and no chorion. Such insects typically produce few offspring, but the survival rate of progeny is high.
