White fly
Aleyrodidae
Description
Whiteflies are soft-bodied, winged insects closely related to aphids. They can be found in most any region, but they are so tiny that they are usually camouflaged. They can be as small as 1/12 of an inch, and are often found in clusters on the undersides of leaves. They are active during the daytime, so they are easier to spot than some other nocturnal pests. Whiteflies are capable of over wintering and reproducing throughout the year in warmer climates.
Symptoms
Whiteflies ingest plant juices and in turn produce a sticky substance known as honeydew. Honeydew left on its own can cause fungal diseases to form on leaves. Plants will become extremely weak and may be unable to carry out photosynthesis. Leaves may dry out and turn yellow, and growth will be stunted. Check undersides of leaves around the veins for flies, even if they aren’t visible, feel leaf surfaces for honeydew.
