Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.
Psyllidae, the jumping plant lice or psyllids, are a family of small plant-feeding insects that tend to be very host-specific, i.e. each plant-louse species only feeds on one plant species (monophagous) or feeds on a few closely related plants (oligophagous). Together with aphids, phylloxerans, scale insects and whiteflies, they form the group called Sternorrhyncha, which is considered to be the most "primitive" group within the true bugs (Hemiptera). They have traditionally been considered a single family, Psyllidae, but recent classifications divide the group into a total of seven families; the present restricted definition still includes more than 70 genera in the Psyllidae. Psyllid fossils have been found from the Early Permian before the flowering plants evolved. The explosive diversification of the flowering plants in the Cretaceous was paralleled by a massive diversification of associated insects, and many of the morphological and metabolic characters that the flowering plants exhibit may have evolved as defenses against herbivorous insects.
The Miridae are a large and diverse insect family at one time known by the taxonomic synonym Capsidae. Species in the family may be referred to as capsid bugs or "mirid bugs". Common names include plant bugs, leaf bugs, and grass bugs. It is the largest family of true bugs belonging to the suborder Heteroptera; it includes over 10,000 known species, and new ones are being described constantly. Most widely known mirids are species that are notorious agricultural pests that pierce plant tissues, feed on the sap, and sometimes transmit viral plant diseases. Some species however, are predatory.
The Cimicomorpha are an infraorder of insects in the order Hemiptera, the true bugs. The rostrum and other morphology of all members apparently is adapted to feeding on animals as their prey or hosts. Members include bed bugs, bat bugs, assassin bugs, and pirate bugs.
Capsus ater is a species of bug in the Miridae family that likely originated in North America, but that is now found in Europe and across the Palearctic to Siberia and in North America.
Orthotylus is a genus of bugs from the family Miridae. There are more than 300 described species worldwide. The sheer number of species has led to the recognition of subgenera and groups, some of which may be promoted to genus level. Yamsunaga recognized the genus as non-monophyletic, and without consistent diagnostic characteristics.
Deraeocoris brevis is a species of predatory plant bug in the family Miridae. It is native to North America where it feeds on plant pests in apple and pear orchards.
