The young of ovoviviparous [[amphibian]]s are sometimes born as larvae, and undergo [[metamorphosis]] outside the body of the mother, and in some insect species, such as the [[tachinidae|tachinid flies]], the embryos develop to the first larval [[instar]] stage before they are laid and the eggs hatch almost immediately.
