Mealybug is the common name of insects in Pseudococcidae, a family of unarmored scale insects found in moist, warm climates. They are considered pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

Mealybugs are sexually dimorphic, meaning that the sexes have distinct morphological differences. Females are nymphal, exhibit reduced morphology, and are wingless. The females do not go change completely and are likely to be neotonic (exhibiting nymphal characteristics). Males are winged and go change completely during their lives. Since mealybugs (as well as all other Hemiptera) are hemimetabolous insects, they do not undergo complete metamorphosis in the true sense of the word. I.e. there are no clear larval, pupal and adult stages, and the wings do not develop internally. However, male mealybugs do exhibit a radical change during their life cycle, changing from wingless, ovoid nymphs to "wasp-like" flying adults.

Mealybug females feed on plant sap. They attach themselves to the plant and secrete a powdery wax layer (therefore the name mealybug) used for protection while they suck the plant juices. The males on the other hand, are short-lived as they do not feed at all as adults and only live to fertilize the females. Male citrus mealy bugs fly to the females and resemble fluffy gnats. Wax has traditionally referred to a substance that is secreted by bees (beeswax) and used by them in constructing their honeycombs. ...

Some species of mealybug lay their eggs in the same waxy layer used for protection in quantities of 50–100; other species are born directly from the female. In biology, a species is the basic unit of biodiversity. ... An average Whooping Crane egg is 102 mm long, and weighs 208 grams A baby tortoise emerges from a reptile egg. ...

The most serious pests are mealybugs that feed on citrus; other species damage sugarcane, grapes, pineapple, coffee trees, cassava, ferns, and orchids. Mealybugs also infest some species of carnivorous plant such as Sarracenia (pitcher plants), in which case they are virtually impossible to eradicate without repeated applications of insecticide such as diazinon.
