"My question is why do ladybugs have spots?" -Owen, 4, Seattle, Washington.

We think of ladybugs as red with black or white spots, but those only represent a quarter of the species of ladybugs. "There are other ladybugs that are black, brown, white, even other colors like yellows," says McFarland.

"The patterns are on them as a warning to birds and other predators that they might not want to eat them because they taste poorly."

Some ladybugs are named after the number of spots they have, like the nine-spotted lady bug, or the seven-spotted ladybug, or even a 20-spotted ladybugs. "But sometimes within those groups they can have a variety of spots, or even no spots, or a dozen or more spots!"
 

"How many different types of ladybugs are there?" -Hallelujah, Kigali, Rwanda

There are over 5,000 different species of ladybugs in the world. And there are about the same number of types of dragonflies and damselflies! We explain a lot more about both insects in our episode. Give it a listen!
