IT IS!!!
it IS giving birth. aphids are vivaporous, meaning that they give live birth. evry one of those 'little' aphids is a clone of the mother. only when the aphid 'colony' is overcrowded will the female leave and then find a mate and mate.
its awesome. aphids have such a complicated reproductive cycle
