How do you know when ladybugs are eating?

You can tell when ladybugs are eating by observing their behavior; they often remain in one place, using their mouthparts to chew on aphids or other small pests. You might also notice them moving slowly and occasionally pausing while they feed. Additionally, if you see a significant decrease in aphid populations on plants where ladybugs are present, it's a good indication they are actively eating.
