Yingabruxia apicalis
Yingabruxia apicalis is a species of flea beetle (Chrysomelidae: Galerucinae: Alticini) in the genus Yingabruxia. The genus Yingabruxia was established relatively recently in leaf beetle systematics. As a member of the Alticini, this species possesses the enlarged hind femora characteristic of flea beetles that enable jumping locomotion. No specific ecological or biological studies have been published on this species.
Zabrotes chavesi
Zabrotes chavesi is a small leaf beetle in the family Chrysomelidae, described by Kingsolver in 1980. The species was named in honor of Franklin Chaves, director of Santa Rosa National Park in Costa Rica, which serves as its type locality. It is distributed across the Americas from northern South America through Central America to the southwestern United States.
Zeugophora
Zeugophora is a genus of leaf beetles in the family Megalopodidae, established by Kunze in 1818. The genus contains multiple species distributed across the Northern Hemisphere, with particularly well-documented diversity in China. Species are phytophagous, with larvae and adults feeding on foliage of specific host plant families. The genus is divided into subgenera based on morphological traits and host associations: subgenus Zeugophora primarily associated with Salicaceae, and subgenus Pedrillia with Celastraceae, Symplocaceae, and Lamiaceae. Male genitalia morphology serves as a critical diagnostic tool for species identification.
Zeugophora abnormis
Zeugophora abnormis is a species of leaf beetle in the family Megalopodidae, first described by John Lawrence LeConte in 1850. It is native to North America, with records from western Canada (Alberta, British Columbia) and the United States. The genus Zeugophora belongs to the small family Megalopodidae, which is closely related to Chrysomelidae (leaf beetles) and contains species with larvae that bore into plant stems or feed externally on foliage.
Zeugophora varians
Zeugophora varians is a species of megalopodid leaf beetle in the family Megalopodidae. It was described by Crotch in 1873. The species is found in North America, with records from Canada including Alberta and British Columbia. Megalopodid beetles are a relatively small family of leaf-feeding beetles closely related to Chrysomelidae.
Zygogramma
Zygogramma is a large genus of leaf beetles in the subfamily Chrysomelinae, comprising approximately 100 species with 13 species occurring north of Mexico. The genus is characterized by its association with plants in the family Asteraceae, particularly ragweeds (Ambrosia) and related genera. Several species, especially Z. bicolorata, have been extensively studied and deployed as biological control agents against invasive weeds. The genus is distinguished from related genera such as Calligrapha by fused tarsal claws.
Zygogramma conjuncta
Zygogramma conjuncta is a leaf beetle in the family Chrysomelidae, first described by Rogers in 1856. It belongs to a genus of leaf-feeding beetles distributed across the Americas, with several species known for their association with specific host plants. The species has been recorded from North America and Middle America, though its taxonomic status is marked as doubtful in some databases. Like other members of Zygogramma, it likely exhibits the typical dome-like body shape and patterned elytra characteristic of the genus.
Zygogramma conjuncta conjuncta
Zygogramma conjuncta conjuncta is a leaf beetle in the family Chrysomelidae, subfamily Chrysomelinae. The genus Zygogramma is distributed across North and South America, with several species recognized as specialist feeders on plants in the family Asteraceae. Members of this genus are characterized by fused tarsal claws, distinguishing them from related genera such as Calligrapha. The subspecies is found in Middle and North America, though specific ecological details for this subspecies are not well documented in available sources.
Zygogramma conjuncta pallida
Zygogramma conjuncta pallida is a subspecies of leaf beetle in the family Chrysomelidae, native to North and Middle America. As a member of the subtribe Doryphorina, it shares morphological traits with other Zygogramma species, including fused tarsal claws that distinguish the genus from related genera such as Calligrapha. The species Zygogramma conjuncta has been associated with feeding on plants in the family Malvaceae. The subspecies epithet "pallida" suggests a lighter coloration compared to the nominate form.
Zygogramma heterothecae
Zygogramma heterothecae is a leaf beetle species in the family Chrysomelidae, first described by Linell in 1896. It belongs to a genus of leaf-feeding beetles primarily found in the Americas. Members of the genus Zygogramma are typically associated with specific host plants and exhibit characteristic elytral patterns with stripes or spots. The genus is taxonomically distinguished from related genera such as Calligrapha by fused tarsal claws.
Zygogramma signatipennis
Zygogramma signatipennis is a leaf beetle in the family Chrysomelidae found in Mexico. The species has been documented feeding on acahual plants (Tithonia tubaeformis, Asteraceae), causing moderate to severe defoliation damage specifically to this host. Research suggests it shows greater feeding preference for plants in the vegetative stage and has been proposed as a potential biological control agent for management of T. tubaeformis as a weed. The species was originally described by Stål in 1859.
