Sometimes we find insects in places we did not expect.
Mealybugs suck the juices from plants. They excrete the excess plant juices in the form of honeydew, which is a wet, sticky fluid. Scientists speculate the waxy covering helps prevent them from drowning in their own honeydew.
It turns out that scientists have already discovered that different species of mealybugs have an affinity for sprouting potatoes. In fact, people rearing mealybugs for experiments, or to produce biological control agents, use sprouting potatoes to maintain their laboratory colonies.
