Aphids

Aphids are small soft-bodied insects that come in many colors and live on a variety of plants. They are members of the insect family Aphididae and the insect order Hemiptera. Their close relatives include psyllids, whiteflies, adelgids, and phylloxerans. Another name for aphids is plant lice because they parasitize the plants they inhabit. They are generally pear shaped and they have what looks like two tailpipes called cornicles on their back end. Like many other insects, aphid species prefer certain types of plants in their diet and so they are usually found associated with those types of plants.
