Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the superfamily Coccoidea. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 described species.
Camptosaurus is a genus of plant-eating, beaked ornithischian dinosaurs of the Late Jurassic period of western North America. The name means 'flexible lizard'.
Saurophaganax is a genus of allosaurid dinosaur from the Morrison Formation of Late Jurassic Oklahoma, United States. Some paleontologists consider it to be a junior synonym and species of Allosaurus. Saurophaganax represents a very large Morrison allosaurid characterized by horizontal laminae at the bases of the dorsal neural spines above the transverse processes, and "meat-chopper" chevrons. The maximum size of S. maximus has been estimated at anywhere from 10.5 meters (34 ft) to 13 meters (43 ft) in length, and 3 metric tons to 4.5 metric tons in weight.
The broad-billed parrot or raven parrot is a large extinct parrot in the family Psittaculidae. It was endemic to the Mascarene island of Mauritius in the Indian Ocean east of Madagascar. It is unclear what other species it is most closely related to, but it has been classified as a member of the tribe Psittaculini, along with other Mascarene parrots. It had similarities with the Rodrigues parrot, and may have been closely related.
The Margarodidae or ground pearls are a family of scale insects within the superfamily Coccoidea. Members of the family include the Polish cochineal and Armenian cochineal and the original ground pearl genus, Margarodes. Beginning in 1880, a number of distinct subfamilies were recognized, with the giant coccids being the first. Although Maskell proposed a new family, many continued to regard the monophlebids as a mere subfamily for many years, and the Margarodidae classification continued to be polyphyletic through the 20th Century. Since then, taking the advice of Koteja several subfamilies and tribes have been elevated into their own families such as Matsucoccidae and Xylococcidae. The pared-down family of Margarodidae is monophyletic.
Kepodactylus is an extinct genus of ctenochasmatid pterodactyloid pterosaur from the Kimmeridgian-Tithonian-age Upper Jurassic Morrison Formation of Colorado, United States.
The Natal free-tailed bat is a species of bat in the family Molossidae, the free-tailed bats. It is native to the islands of Mauritius and Réunion. It is known from fewer than five locations in its range, but it is common at a few sites. It roosts in caves, and it is considered to be an endangered species due to disturbance of its cave habitat.
Paratachardina pseudolobata, the lobate lac scale, is a polyphagous and pestiferous lac scale insect, which damages trees and woody shrubs in Cuba, Florida, the Bahamas and the Australian territory of Christmas Island. It was mistakenly identified as Paratachardina lobata (Chamberlin), an insect native to India and Sri Lanka, but was in 2007 recognized and named as a distinct species based on material from Florida; its native distribution is as yet unknown. The new lac insect was described based on all stages of the female, during the revision of the genus Paratachardina, wherein all its known species were redescribed.
Conchaspis capensis is a species of scale insect from South Africa found on Metalasia muricata and Phylica species. It was originally described by Carl Linnaeus in his 1763 work Centuria Insectorum.
Conchaspididae is a small family of scale insects known as false armoured scales because of their resemblance to Diaspididae.
Coccus is a genus of scale insects in the family Coccidae. Several species, such as Coccus viridis, a major pest of coffee, are important agricultural pests. The type species is Coccus hesperidumLinnaeus.
Eriococcidae is a family of scale insects in the order Hemiptera. They are commonly known as felt scales or eriococcids. Each species is usually specific to a different plant host, or closely related group of hosts.
Newsteadia myersi is the only member of the scale insect family Ortheziidae to have been found in New Zealand. It was found by sifting through the leaf litter and debris under nikau palm trees.
Phenacoleachiidae is a family of scale insects commonly known as the phenacoleachiids. They are found only in the South Island of New Zealand, and on certain offshore islands. There are two species in a single genus.
Putoidae is a family of scale insects commonly known as giant mealybugs or putoids. There is probably a single genus, Puto, containing about sixty species. The genus name Macrocerococcus has also been used but it is now considered to be a synonym of Puto. The genus Puto was formerly classified as a member of the Pseudococcidae; however, it so significantly differed from the rest of the Pseudococcidae that it was accorded its own family Putoidae.
Cylindrococcus is a genus of scale insects that induces galls on plants of the genus Allocasuarina. There are two described species of Cylindrococcus, both of which occur only in Australia. The galls of adult females look somewhat similar to the cone-like "fruit" of the host plant and might be mistaken for such.
Callococcus is a genus of Australian scale insect that feeds on species of Leptospermum, Hypocalymma, Kunzea and some other members of the tribes Chamelaucieae and Leptospermeae in the myrtle family Myrtaceae. Callococcus leptospermi induces stem-swelling galls on some species of Leptospermum, and it is considered to be a potential biological control agent of Leptospermum laevigatum in South Africa. The other described species of Callococcus do not induce galls.
Trabutina mannipara, or mana scale, is a species of mealybug found in the Middle East and southern Europe. It is the most well-known of the five species in the genus Trabutina, of which it is the type species, due to its association with the biblical story of manna. T. mannipara feeds parasitically on tamarisk trees, and excretes a sweet substance which is sometimes collected for human consumption. Obsolete terms for it include Coccus manniparus and Trabutina palestina. This species can be found in the Sinai and Iraq.
Newsteadia floccosa, the boreal ensign scale, is a species of scale insect in the family Ortheziidae. It is native to Europe and is found in the soil and amongst plant litter and mosses on the ground.
Antecerococcus is a genus of scale insects. They are found worldwide but with greater abundance in the Old World. There are about 56 species:
