As their name
implies, whiteflies are in fact...tiny white colored
flies. They are about 1/8 of an inch long and are
found feeding on the bottom of leaves of many types
of plants. The wings of the adults are covered with
a powdery substance that gives them their white
color.
These sucking insects
can cause a lot of damage whenever they build up to
large numbers. Their droppings (honeydew) may cause
the appearance of sooty mold on leaves and plant
parts beneath where they are feeding. At times, they
may act as a vector for the spread of diseases as
they go from plant to plant.
