Q. Are all ladybugs girls?
A. No. There are boy ladybugs and girl ladybugs. It's almost impossible for the average person to tell them apart. But here are some clue that might help. First, females are usually larger than males. Second, if you observe one ladybug riding atop another ladybug, they are in the process of mating. A male ladybug will grab the female's elytra (hard wings) and holds on tight. There are photos on the Ladybugs Mating Page to help you. An entomologist (bug scientist) can see the difference between males and females under a microscope.
Q. What are boy ladybugs called?
A. Boy ladybugs are called ladybugs, too.
