Unfortunately, there’ nearly 5,000 different aphid species spread across the world: black aphids, green aphids, yellow aphids, red aphids, even white aphids too!
Aphids are very small insects that live in large colonies and feed on plant sap. Most aphids are specialized to feed on a specific type of plant, although a few species can feed on hundreds of unrelated plants.
Aphids usually feed passively on sap of phloem vessels in plants, as do many of other hemipterans such as scale insects and cicadas. Once a phloem vessel is punctured, the sap, which is under pressure, is forced into the aphid's food canal.
