Order:  Hemiptera
Family:  Aphididae
Diet:  Plant sap.
Vegetation Association:   Very plant specific.  Each individual species can usually only live off of certain host plants; i.e. oleander, milkweed, etc.  Each colony on a plant is started by a single female; when the colony gets crowded young develop into winged adults that go through a flying period before finding a new plant.  The colonies extract liquids from plants, which may cause the curling of leaves or even death.
Predators:  Lady beetles, lady bugs, lady birds, hoverfly larvae, lacewings, and parasites.
Life Stages:  Parthenogenesis, a process by which the eggs develop without fertilization by a male and hatch into genetic replicas of the mother.
Notes:  Also known as plant lice.  They can transmit plant viruses to their food plants which may kill the plants.  They are small enough to be transported by wind.  They produce anal secretions or “Honeydew” that attract many species of ants.
