ii. HAEMOCOELOUS VIVIPARITY This involves embryos developing free in the female's haemolymph with nutrients taken up by
osmosis. This form of
internal parasitism occurs only in sterpsiptera and some gall midges.
v. ADENOTROPHIC VIVIPARITY
This occurs when a poorly developed larva hatches and feeds orally from accessory (milk) gland
secretion within the uterus of the mother's reproductive system. The full grown larva is deposited
and
pupariates immediately (eg) tsetse flies, louse or wallaby flies, bat flies.
