Guides
Agonoscelis
Agonoscelis is a genus of shield bugs (Pentatomidae) in the monotypic tribe Agonoscelidini. The genus contains approximately 19–22 species native to the Afrotropics and Australia, with one species, A. puberula, established in the New World. Several species are agricultural pests of sorghum, sunflower, and other crops. Adults range from 8 to 12 mm in length and possess five nymphal stages.
Bagrada hilaris
Bagrada bug, Painted bug
Bagrada hilaris is an invasive shield bug native to Africa and Asia that has become a significant agricultural pest in North America, South America, and Europe. First detected in the Western Hemisphere in Los Angeles in 2008, it has since spread throughout California, Arizona, and other southwestern states, as well as establishing in Chile and Italy. The species is a major pest of Brassicaceae crops including cabbage, kale, broccoli, and cauliflower, causing damage through sap-sucking by both adults and nymphs. Its rapid spread and broad host range have made it a priority for integrated pest management research.
Chlorochroa norlandorum
Chlorochroa norlandorum is a species of stink bug in the family Pentatomidae, order Hemiptera. It belongs to the genus Chlorochroa, which includes several species commonly known as conchuela or green stink bugs. The species name suggests a connection to the Norland region, though specific details about its biology and distribution remain poorly documented in the scientific literature. As with other members of the genus, it is likely a plant-feeding species with piercing-sucking mouthparts.
Chlorochroa saucia
Conchuela stink bug
Chlorochroa saucia is a species of stink bug in the family Pentatomidae, commonly known as the conchuela stink bug. Adults reach approximately 9 mm in length. The species is distributed across North America and has been documented as a pest of developing grain in sorghum heads, where it feeds on kernels using piercing-sucking mouthparts. It is also known to occur on alfalfa, corn, cotton, peppers, tomatoes, and various fruits, with mesquite serving as a common weed host. The species has been observed as prey of the predatory wasp Astata unicolor.
Coenus delius
Coenus delius is a stink bug species in the family Pentatomidae, first described by Thomas Say in 1832. It belongs to the genus Coenus, a small group of pentatomid bugs. The species is documented across North America with over 500 iNaturalist observations.
Dendrocoris pini
Dendrocoris pini is a species of stink bug in the family Pentatomidae, described by Montandon in 1893. It belongs to the genus Dendrocoris, a group of arboreal stink bugs associated with coniferous trees. The species is found in North America. Like other members of its genus, it is likely associated with pine trees, though specific ecological details remain poorly documented in published literature.
Euschistus servus euschistoides
brown stink bug
Euschistus servus euschistoides is a subspecies of brown stink bug in the family Pentatomidae. It is a nominal phytophage documented to exhibit facultative predatory behavior on caterpillars. The subspecies occurs in North America and is part of the Euschistus servus species complex, which includes agricultural pests of soybean and other crops. Observations in central New York State confirmed predation on Pieris rapae larvae.
Euschistus variolarius
one-spotted stink bug, onespotted stink bug
Euschistus variolarius, commonly known as the one-spotted stink bug, is a Nearctic species of shield bug in the family Pentatomidae. It is a phytophagous insect that feeds primarily on seeds and developing fruits of various plants, including legumes, grasses, and agricultural crops such as soybean and alfalfa. The species produces one generation per year in northern parts of its range, with adults overwintering in ground debris and emerging in spring to reproduce. While historically considered a minor pest, it has become increasingly recognized as an emerging pest in Midwestern soybean and corn production.
Halyomorpha
Halyomorpha is a genus of shield bugs (family Pentatomidae) in the subfamily Pentatominae and tribe Cappaeini, erected by G. Mayr in 1864. The genus likely originated in Asia. Halyomorpha halys, the brown marmorated stink bug, is the most well-known species and has become a globally significant invasive pest. The genus is characterized by shield-shaped bodies typical of pentatomids.
Holcostethus abbreviatus
Holcostethus abbreviatus is a species of stink bug in the family Pentatomidae, first described by Uhler in 1872. It is distributed across Central America and North America. The species is part of the genus Holcostethus, which comprises small to medium-sized pentatomid bugs. Based on iNaturalist records, it has been documented in at least 415 observations.
Lineostethus tenebricornis
Lineostethus tenebricornis is a stink bug species in the tribe Discocephalini, originally described by Ruckes in 1957. The species belongs to a genus characterized by a distinctly discoid (rounded, disc-shaped) head, a trait typical of discocephaline pentatomids. It was one of four species included in the 2018 taxonomic revision of Lineostethus, which provided updated morphological descriptions and identification keys.
Mecidea major
Mecidea major is a grass-feeding stink bug in the family Pentatomidae. A detailed life history study in southern New Mexico documented year-round activity of adults and nymphs, including winter months—unusual for a pentatomid. The species is bivoltine with a possible partial third generation. Five nymphal instars have been described and can be distinguished by body size and wing pad development.
Mormidea lugens
Mormidea lugens is a small stink bug in the family Pentatomidae, distributed across the Caribbean, Central America, and eastern North America. In southern Illinois, it exhibits a univoltine life cycle with adults overwintering and emerging in late April, persisting until early November. The species develops on various grasses and sedges, with nymphs feeding on vegetation and adults targeting developing grass seeds. It is considered a potential pest of wheat and other small grains.
Neottiglossa tumidifrons
Neottiglossa tumidifrons is a species of stink bug in the family Pentatomidae, described by Downes in 1928. It is known from North America. Like other members of the genus Neottiglossa, it belongs to a group of small to medium-sized pentatomids. The specific epithet 'tumidifrons' refers to a swollen or enlarged frons (front of the head).
Odmalea
Odmalea is a genus of stink bugs in the family Pentatomidae, established by Bergroth in 1915. The genus contains at least three described species. Members are true bugs in the order Hemiptera, characterized by piercing-sucking mouthparts and shield-shaped bodies typical of the family.
Piezodorus lituratus
gorse shield bug
Piezodorus lituratus, commonly known as the gorse shield bug, is a shield bug species in the family Pentatomidae. Adults reach 10–13 mm in length and exhibit seasonal color polymorphism: bright green in spring after emergence from hibernation, developing purplish-red markings on the pronotum and corium in late summer, and becoming paler before hibernation. The species is associated with leguminous host plants, particularly broom and dyer's greenweed, and is found across Europe, Africa, Northern Asia, and North America.
Trichopepla grossa
Trichopepla grossa is a species of stink bug in the family Pentatomidae, order Hemiptera. The genus Trichopepla is characterized by hairy or setose bodies, distinguishing it from many other pentatomid genera. Very limited information is available for this particular species, with only three observations recorded on iNaturalist. The species epithet "grossa" (Latin for "thick" or "coarse") likely refers to the robust body form or prominent setae typical of the genus.
