Black aphid. Coloured scanning electron micrograph of a black aphid (Aphis sp.) feeding on sap from a plant stem. Aphids feed off the sugary sap of plant stems and leaves by inserting their tube-like stylet into the plant's veins. This can cause the leaves to yellow,wilt and finally die. Aphids excrete sweet waste fluids (honeydew) which is sometimes collected as food by ants. Aphids are serious plant pests of certain crops,flowers and houseplants.
