This episode, “Homopterans on Parade,” is about four groups of small plant-juice-suckers that grace (and sometimes damage) our vegetation.

Aphids consume plant juice. Lots and lots of plant juice. The majority of aphids are picky eaters who are attracted to a particular plant species or family. Entertaining a few aphids won’t compromise a plant, but hosting a whole battalion can damage the plant or impair the production of seeds. As an aphid feeds on plant sap, it excretes the unneeded portion in the form of small drops of honeydew.
