How do you defeat an army single-handedly?
Aphids are right at the top of the menu for ladybugs. Unfortunately they are protected by a whole army of ants, which use the aphids’ secretions as a source of nutrition. But the ants’ attacks with pincers, claws, and acid cocktails don’t faze ladybugs: Their body is designed so that the ants’ sharp mandibles glide over the smooth red wing cases without causing any damage. In addition, ladybugs can completely retract their legs under their round body and simply ride out the attack.
