Ladybugs are cannibals
Ladybugs are cannibals
SERHII HROMOV/SHUTTERSTOCK

These brightly coloured beetles aren’t afraid to turn on each other when food is scarce. If it’s a matter of survival, adult ladybugs will eat other freshly moulted or newborn ladybugs. The beetles also have a wicked defence mechanism: When startled, ladybugs emit a foul-smelling fluid from their leg joints that helps scare away predators.
