The male has an insect penis which is called an aedeagus. A “lock and key” fit means that if he gets it wrong and tries to mate with another species of ladybug, he will not get to third base! Fertilization, as you can see, is internal, which surprises many people. It doesn’t exactly start with a kiss, but with a little Barry White in the background this could almost be classed as romantic! Almost, but not quite!
