Adult Asian citrus psyllids are small (3-4 mm) with mottled brown wings and are active, jumping insects. The eggs are bright yellow and are deposited on newly emerging plant tissue. Nymphs are green or dull orange, and feed on young leaves and stems.  The Asian citrus psyllid itself is not a major pest of citrus; however, it is known to be a vector of citrus greening disease (CGD), a very serious bacterial disease of citrus. There is no known cure for CGD and tree removal is the only control option.
