The Aphid's reproductive cycle is so fast that females are born pregnant.
You're Expecting What?
Human reproductive technology has certainly stood the scientific world on its head over the last 30 years, but in Nature, some of the ways that life on Earth regenerates, is downright strange.
Aphids are born pregnant. In fact, they are pregnant before they are born. The common aphid, of which there are 4400 species, produces only female offspring, which are already pregnant with the next generation, allowing for quick multiplication of their numbers. In their growing phase, they may become males, or remain asexual.
