Blissus arenarius
Blissus arenarius is a species of true bug in the family Blissidae, first described by Barber in 1918. It is a member of the chinch bug genus Blissus, which contains several economically significant agricultural pests. The species is known to occur in North America and has two recognized subspecies: B. a. arenarius and B. a. maritimus. Like other Blissus species, it is associated with grassland and sandy habitats.

Blissus barberi
Blissus barberi is a species of chinch bug in the family Blissidae, described by Leonard in 1968. It belongs to a genus containing several economically significant pests of cereal crops and turfgrass. The species is part of a taxonomic group whose members are characterized by piercing-sucking mouthparts and association with grasses. Specific biological and ecological details for B. barberi remain poorly documented in the available literature.

Blissus canadensis
Blissus canadensis is a species of true bug in the family Blissidae, described by Leonard in 1970. It belongs to a genus containing several economically important chinch bug species that are pests of turfgrass and agricultural crops. The species is recorded from the northern Great Plains region of North America.

Blissus insularis
Southern Chinch Bug
Blissus insularis, the southern chinch bug, is a true bug in the family Blissidae that is a major pest of St. Augustinegrass (Stenotaphrum secundatum). It is native to North America and has been introduced to Oceania, including Hawaii. The species harbors specialized midgut crypts that host dense populations of Burkholderia bacterial symbionts, which are essential for host fitness and development. It is economically significant as a turfgrass pest, causing damage through piercing-sucking feeding that leads to yellowing and death of grass patches.

Blissus leucopterus hirtus
Hairy Chinch Bug
Blissus leucopterus hirtus is a subspecies of chinch bug recognized as a significant pest of grain crops, particularly wheat. It is distinguished from the nominate subspecies B. l. leucopterus by morphological features including denser body hair. The taxon is included in quarantine pest lists due to its potential for economic damage and invasive spread. Mathematical modeling indicates high probability of acclimatization in southern and central regions of Russia.

Blissus minutus
Blissus minutus is a small true bug in the family Blissidae, described by Blatchley in 1925. The species is poorly documented in available sources, with minimal published information on its biology, ecology, or economic significance. It belongs to a genus containing several economically important chinch bug species that damage cereal crops and turf grasses, though B. minutus itself has not been specifically implicated in agricultural pest literature.

Blissus occiduus
Western Chinch Bug
Blissus occiduus, the western chinch bug, is a phloem-feeding true bug (Hemiptera: Blissidae) that is a significant pest of warm-season turfgrasses, particularly buffalograss and zoysiagrass. The species exhibits strong host preference hierarchies, with buffalograss being the most preferred host followed by zoysiagrass, though it can survive and reproduce on a broad range of grasses including agronomic crops. Field studies have documented inconsistent control with neonicotinoid insecticides, with thiamethoxam showing particularly rapid degradation in buffalograss tissues compared to imidacloprid and clothianidin.

Blissus sweeti
Blissus sweeti is a species of true bug described by Leonard in 1968. It belongs to the family Blissidae, a group commonly known as chinch bugs. The species has been documented in Central America and North America. Like other members of the genus Blissus, it is likely associated with grassland or agricultural habitats, though specific ecological details remain poorly documented.

Ischnodemus
Wheat Chinch-bugs
Ischnodemus is a genus of true bugs in the family Blissidae containing approximately 95 species. Adults are characterized by moderately to very elongated bodies, reflected in the genus name derived from Greek for 'feeble body.' The genus has a cosmopolitan distribution across all major zoogeographic regions and shows strong associations with grasses (Poaceae), with some species utilizing sedges (Cyperaceae). Several species are economically significant, including I. variegatus (Myakka bug), an introduced species in North America being evaluated as a biological control agent for invasive West Indian marsh grass.

Ischnodemus conicus
Ischnodemus conicus is a species of true bug in the family Blissidae, first described by Van Duzee in 1909. It is found in North America, with confirmed records from the United States. The genus Ischnodemus belongs to the lygaeoid superfamily, a group of seed bugs and chinch bugs. Specific ecological details about this species remain poorly documented in available sources.

Ischnodemus hesperius is a species of true bug in the family Blissidae, described by Parshley in 1922. It is part of a genus whose members are commonly known as chinch bugs, many of which are associated with grasses and sedges. The species has been documented in North America, with specific records from the United States and Manitoba, Canada. Published information on its biology and ecology remains limited.

myakka bug
Ischnodemus variegatus, commonly known as the myakka bug, is a true bug in the family Blissidae native to Central and South America. The species was first recorded in Florida in 2000, where it was discovered feeding on the invasive West Indian marsh grass (Hymenachne amplexicaulis) in Myakka River State Park. It has been extensively studied as a potential biological control agent for this invasive wetland weed due to its high host specificity. The bug is small, with females reaching about 7 mm and males about 6 mm in length, and produces a noxious scent when disturbed.
