Psyllids are insects that are related to aphids. They form winged adults that are small and brownish to green in color. When they spring into flight, they are propelled by powerful hind legs.

The immature form of the psyllid is wingless and is often covered with white, waxy threads or drops of honeydew. They damage plants by sucking sap of shoots and leaves. This often leaves these parts distorted and stunted. In extreme cases, the tips of stems may die.

As with many sucking insects, psyllids may sometimes transmit virus and other diseases from plant to plant. Some types form galls on leaves and the immature forms feed on the inside of the gall.

The control of psyllids is similar to that for aphids.
