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.
Aralia spinosa, commonly known as devil's walking stick, is a woody species of plant in the genus Aralia, family Araliaceae, native to eastern North America. The various names refer to the viciously sharp, spiny stems, petioles, and even leaf midribs. It has also been known as Angelica-tree.

The brown marmorated stink bug is an insect in the family Pentatomidae, native to China, Japan, Korea and other Asian regions. In September 1998 it was collected in Allentown, Pennsylvania, where it is believed to have been accidentally introduced. The nymphs and adults of the brown marmorated stink bug feed on over 100 species of plants, including many agricultural crops, and by 2010–11 had become a season-long pest in orchards in the Eastern United States. In 2010, in the Mid-Atlantic United States, $37 million in apple crops were lost, and some stone fruit growers lost more than 90% of their crops. Since the 2010s, the bug has spread to the nation of Georgia and Turkey and caused extensive damage to hazelnut production. It is now established in many parts of North America, and has recently become established in Europe and South America.
Rhagoletis mendax is a species of tephritid fruit fly known by the common name blueberry maggot. The blueberry maggot is closely related to the apple maggot, a larger fruit fly in the same genus. It is a major pest of plant species in the Ericaceae family, such as blueberry, cranberry, and huckleberry. The larva is 5 to 8 mm long, apodous, and white with chewing mouthparts. Female adults are 4.75mm in length, males are slightly smaller. Both adults are mostly black in color with white stripes, orange-red eyes, and a single pair of clear wings with black banding. The adult female fly lays a single egg per blueberry, and when the larva hatches it consumes the fruit, usually finishing the entire berry in under 3 weeks and rendering it unmarketable. The larva then falls to the soil and pupates. Adult flies emerge, mate, and females oviposit when blueberry plants are producing fruit. Each female fly can lay 25 to 100 eggs in their lifetime.
Callipogon relictus is a species of longhorn beetle which is mostly found in Korea, but also in China and southern part of Russian Far East. It inhabits mixed and deciduous forests. The population of Callipogon relictus is decreasing due to deforestation and uncontrolled collection, and therefore the species are listed in the Russian Red Book.
Zelus renardii, commonly known as the leaf hopper assassin bug, is a predacious insect contained within tribe Harpactorini. Diurnal and found on both wild and crop plants, Z. renardii has spread from its native habitats in western North and Central America into three other biogeographic regions across the globe.
Chrysaster ostensackenella is a moth of the family Gracillariidae. It is known from Ontario, Québec and Nova Scotia in Canada, and the United States. It has also been recorded in 2015 from China and in 2017 from Korea, and in 2022 from Central Italy.
Diaphorina citri, the Asian citrus psyllid, is a sap-sucking, hemipteran bug in the family Psyllidae. It is one of two confirmed vectors of citrus greening disease. It has a wide distribution in southern Asia and has spread to other citrus growing regions.
The common flowerbug is a common minute pirate or flower bug.
Lymantria dispar asiatica, the LDA moth or Asian spongy moth, also known as the Asian gypsy moth, is a moth in the family Erebidae of Eurasian origin. It is similar to Lymantria dispar dispar in appearance, but adult females can fly. It is classified as a pest and is host to over 500 species of trees, shrubs and plants.
Charitoprepes lubricosa is a moth in the species-rich subfamily Spilomelinae of the family Crambidae. It was described by William Warren in 1896 as the type species of the genus Charitoprepes. The species is known from its type locality in the Indian Khasi Hills as well as from Japan and Korea.
The spotted lanternfly is a planthopper indigenous to parts of China and Vietnam. It has spread invasively to Japan, South Korea, and the United States. Its preferred host is tree of heaven, but it infests economically significant plants including soybean, grapes, stone fruits, and Malus spp. In its native habitat, L. delicatula populations are kept in check by parasitic wasps.
Ricania speculum, common name Black planthopper or Ricaniid Planthopper, is a species of planthoppers belonging to the family Ricaniidae.
Drosicha corpulenta is a species of giant scale insect in the family Monophlebidae, in the superfamily Coccoidea. It is native to eastern Asia where it feeds on a range of trees, shrubs and non-woody plants.
Aleurocanthus spiniferus, the citrus spiny whitefly, is an important pest of citrus and tea plants. They are part of the order Hemiptera, and the family Aleyrodidae, where more than 1550 species have been described. A. spiniferus is indigenous to parts of tropical Asia, where it was first discovered in Japan. Since its discovery, it has now spread to numerous continents including Africa, Australia, America, Pacific Islands and Italy. Wherever it is found, it has become a highly destructive pest. Two populations of A. spiniferus have been found according to the plant or crop they infest: the citrus spiny whitefly, as well as the tea spiny whitefly.
Ardisia crispa, the Japanese holly, is a species of flowering plant in the family Primulaceae. It is found in the eastern Himalayas, Assam, southern China, Indochina, Taiwan, Korea, the Ryukyu Islands, and Japan, and has been introduced to Queensland, Australia, and the Windward Islands in the Caribbean. An evergreen perennial shrub reaching at most 1.5 m (5 ft), it is often sold as an ornamental for its dark green leaves and long‑lasting red berries, much like Ardisia crenata, the Christmas berry or coralberry.
