Leaves show a characteristic curling, similar to damage caused by viruses. Heavily infested plants have shortened internodes leading to resetting or a "bunchy top" appearance. A heavy, black, sooty mold may develop on an infested plant's leaves and stems as a result of the mealybug's heavy honey-dew secretions.

Larvae feed on the roots of the emerging plants, which causes the most damage since the young plants are more vulnerable. [1] In the adult stage the beetles cause damage by eating the flowers, leaves, stems, and fruits of the plant [ 1 ] The beetles can also spread diseases such as bacterial wilt and mosaic virus .

Coreidae is a large family of predominantly sap-sucking insects in the Hemipteran suborder Heteroptera. [1] The name "Coreidae" derives from the genus Coreus, which derives from the Ancient Greek κόρις (kóris) meaning bedbug. [2]

Leafhoppers mainly are herbivores, but some are known to eat smaller insects, such as aphids, on occasion. A few species are known to be mud-puddling, but as it seems, females rarely engage in such behavior. Many species are ...
They generally feed upon plants belonging to the plant orders Rosales and Sapindales, and spend most of their lives in tree leaves and stems. [6] [8] They exhibit incomplete metamorphosis and have lifespans that can be several years. Some tessaratomids guard their eggs and nymphs from predators which may include parasitoid wasps and assassin bugs.
