Anisoscelis
leaf-footed bugs
Anisoscelis is a genus of leaf-footed bugs (Coreidae: Anisoscelini) distributed from the southern United States through Central and South America. The genus currently comprises approximately nine species, though species counts vary due to taxonomic revisions. Members are associated with passion vine plants (Passifloraceae) as host plants. Several species exhibit expanded, leaf-like hind tibial structures. The genus has undergone significant taxonomic revision, with former subgenus Bitta now restored to generic rank.
Chlorocoris distinctus
Chlorocoris distinctus is a species of stink bug in the family Pentatomidae. It occurs across a broad geographic range spanning Central America, North America, and South America. The species has been documented as a host for egg parasitoids in Mexico, though detailed biological studies remain limited.
Cuerna n-sp-ok-i
Cuerna n-sp-ok-i is an undescribed species of sharpshooter leafhopper in the tribe Proconiini, known from Oklahoma. The genus Cuerna includes medium-sized leafhoppers that are part of the diverse egg parasitoid research conducted by Dr. S.V. Triapitsyn and colleagues. Species in this genus are associated with egg parasitoids in the families Mymaridae and Trichogrammatidae, which have been studied extensively for biological control applications. The 'n-sp-ok-i' designation indicates this is a new species awaiting formal description, with the suffix denoting its Oklahoma origin.
Cuerna sayi
Cuerna sayi is a species of sharpshooter leafhopper in the family Cicadellidae, tribe Proconiini, described by Nielson in 1965. It is native to North America and has been recorded as a host for egg parasitoids in the families Mymaridae and Trichogrammatidae. The species is part of the economically important sharpshooter group, some members of which are vectors of plant pathogens including Xylella fastidiosa.
Draeculacephala noveboracensis
Black-ledged Sharpshooter
Draeculacephala noveboracensis is a leafhopper species in the family Cicadellidae, commonly known as the Black-ledged Sharpshooter. It is native to North America and has been documented as a host for egg parasitoids in the families Mymaridae and Trichogrammatidae. The species has been studied in California in relation to biological control programs targeting sharpshooter pests.
Homalodisca insolita
johnsongrass sharpshooter
Homalodisca insolita, commonly known as the johnsongrass sharpshooter, is a proconiine sharpshooter in the family Cicadellidae. It is native to southern North America and has been documented spreading northward into the southeastern United States. The species is a known vector of Xylella fastidiosa, a xylem-limited bacterium that causes Pierce's disease in grapevines and other plant diseases. Its eggs serve as hosts for egg parasitoids including Paracentrobia americana (Trichogrammatidae).
Hortensia similis
Common Green Leafhopper
Hortensia similis is a leafhopper species in the family Cicadellidae, originally described as Tettigonia similis by Walker in 1851. It is commonly known as the Common Green Leafhopper and has a wide distribution across the Americas, from the southwestern United States through Central America to South America. The species has been documented in California, Arizona, the British Virgin Islands, and several South American locations including Amazonas and Bahia. It is an agricultural pest associated with maize cultivation in parts of its range, where it serves as a host for various egg parasitoid wasps.
Leptoglossus zonatus
leaf-footed bug
Leptoglossus zonatus is a polyphagous leaf-footed bug native to the Americas, ranging from the southwestern United States through Central America to South America. Adults measure approximately 20 mm in length with gray coloration, a zigzagging whitish band across the dorsum, and two distinctive yellowish spots on the anterior pronotum that serve as the primary identifying characteristic. The species has emerged as a significant agricultural pest, particularly in California almonds and Gulf Coast satsuma mandarins, causing direct feeding damage and transmitting plant pathogens. Two genetically distinct strains occur in the Western Hemisphere, with low overall genetic diversity suggesting potential for further range expansion.
Megamelus falcatus
Megamelus falcatus is a species of planthopper in the family Delphacidae, first described by Beamer in 1955. The species is known from the northeastern United States, with confirmed records from Connecticut, New Hampshire, and New York. As a member of the genus Megamelus, it is associated with wetland and aquatic habitats. The genus Megamelus is notable for having several species that have been investigated as hosts for egg parasitoids in the family Mymaridae, which are of interest for biological control research.
Oncometopia hamiltoni
Oncometopia hamiltoni is a species of sharpshooter leafhopper in the family Cicadellidae, described by Rakitov in 2016. It belongs to the tribe Proconiini, a group of large, active leafhoppers known for their xylem-feeding habits and distinctive "raining" behavior caused by forceful excretion of excess fluid. The species is part of a genus containing several economically significant sharpshooters that have been studied for their role in plant disease transmission and their interactions with egg parasitoids.
Oncometopia orbona
Broad-headed Sharpshooter
Oncometopia orbona, commonly known as the broad-headed sharpshooter, is a large leafhopper in the family Cicadellidae. It feeds on xylem sap from plants, processing large volumes of nutrient-poor fluid and excreting the excess as honeydew—a behavior that creates the phenomenon of 'raining trees.' The species possesses distinctive white chalky brochosomes on its sides, used to powder egg-laying sites. It is a strong flier with excellent eyesight and serves as a host for egg parasitoids in the family Mymaridae.
Pachnaeus litus
blue-green citrus root weevil, blue-green citrus weevil
Pachnaeus litus is a broad-nosed weevil in the family Curculionidae, commonly known as the blue-green citrus root weevil or blue-green citrus weevil. It is a pest of citrus in North America, with eggs that serve as hosts for multiple parasitoid wasp species. The species has been studied extensively for biological control potential, particularly targeting its egg stage with parasitoids such as Brachyufens osborni (Trichogrammatidae), Pediobius irregularis, and Horismenus bennetti (Eulophidae).
Paraulacizes irrorata
speckled sharpshooter
A large and distinctive North American sharpshooter leafhopper, readily recognizable by its size and speckled pattern. Adults feed on phloem of grasses and are active from early spring through summer. Eggs are laid in woody twigs, stems, or petioles, where they are vulnerable to parasitism by the egg parasitoid *Gonatocerus fasciatus*.
Sagotylus
Sagotylus is a genus of leaf-footed bugs in the family Coreidae, established by Mayr in 1865. The genus contains a single described species, S. confluens. Members of this genus are true bugs (Hemiptera) within the suborder Heteroptera.
