Once a male has found a female to mate with, he will grasp her firmly from behind using the front most part of the leg, called the tarsi. The tarsi is like a serrated claw with sticky pads. The male's genetic material is passed to the female through an ejaculatory gland, much like an oviposititor for the female. The male's genetic material than passes into the female through the oviduct to the spermatheca. This is a special sac in the female's body where the sperm can be stored for upto several months before it is used to fertilize the eggs as they are laid.
Ladybugs tend to lay their eggs where food is abundant.
Once an aphid has been captured, it is off to the digestive system. The manibles, or mouth parts, of the ladybug begin the digestive process by chewing up the aphid. Next, it moves into the foregut, midgut and hindgut for further break down. The movement that takes the aphid from the mouth parts through the body and to eventually be excreted is called peristalsis. It is known as rhythmic muscle contractions.
