| Aphids | Aphids | Aphids are small (1/16" to 1/8"), soft-bodied, sap-sucking insects. Depending on species, their color can vary from green to yellowish to rose-colored or black. Some species may appear powdery or woolly. Adults are winged, but usually most of the infestation consists of wingless individuals. Aphids are often found near the tips of shoots, preferring tender new growth where they may cluster in large groups. They also feed on the underside of leaves and on stems. Heavy aphid infestations can cause wilting and yellowing. New growth may be deformed and stunted. Aphids often produce large amounts of honeydew, a shiny, sticky substance which may accumulate on lower leaves or surfaces below infested plants. Black sooty mold will sometimes grow on the honeydew. While the mold will not harm the plant, it is unsightly and may become a problem on household surfaces. Aphids may be brought into the house on plants or may enter through open windows. They can spread from plant to plant by crawling or flying. |
