Calligrapha verrucosa
Calligrapha verrucosa is a species of leaf beetle in the family Chrysomelidae. It is found in North America, with records from western Canada including Alberta, British Columbia, and Manitoba. As a member of the genus Calligrapha, it likely exhibits the characteristic dome-shaped body and distinctive elytral markings typical of the group, though specific morphological details for this species are poorly documented in the provided sources.
Calligrapha wickhami
Calligrapha wickhami is a leaf beetle species in the subgenus Erythrographa (Coleoptera: Chrysomelidae, Chrysomelinae), distinguished by reddish testaceous coloration extending to dark body parts including elytral markings. It is the only species in this subgenus not found in Mexico, being restricted to southern Texas. The subgenus Erythrographa is endemic to Central America and particularly diverse in the Mexican Transition Zone between the Nearctic and Neotropical realms.
Phaedon
Phaedon is a genus of leaf beetles in the subfamily Chrysomelinae. Species in this genus are associated with feeding on plant foliage, with some species documented as agricultural pests. The genus has been recorded across Europe and Asia, with at least one species, P. brassicae, known from China, Japan, Korea, Taiwan, and Vietnam. Members are small to medium-sized beetles typical of the Chrysomelidae family.
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 suturalis
ragweed leaf beetle
Zygogramma suturalis is a leaf beetle in the family Chrysomelidae, commonly known as the ragweed leaf beetle. Native to North America, it has been introduced to Russia (1978) and other parts of Europe and Asia as a biological control agent for common ragweed (Ambrosia artemisiifolia). The beetle exhibits strong host specificity, feeding almost exclusively on this plant. Despite establishment in introduced ranges, it has achieved only moderate biological success due to low population densities and limited impact on host plant populations.
