Anacampsis consonella
Anacampsis consonella is a small gelechiid moth species originally described by Zeller in 1873. It was long treated as a junior synonym of A. rhoifructella but was reinstated as a valid species based on differences in larval morphology, phenology, and genital structure. The species feeds as a larva on leaves of Viburnum prunifolium (blackhaw viburnum).
Ceruraphis eriophori
Wayfaring Tree-sedge Aphid
Ceruraphis eriophori is an aphid species with a heteroecous life cycle involving host alternation between Viburnum species (primary hosts) and sedges or related plants (secondary hosts). In North America, it has been collected from curled leaves of Viburnum lantana and V. opulus in New Brunswick, and from V. opulus var. roseum in Colorado. The species also occurs in Europe, where secondary hosts include Carex, Eriophorum, Luzula, and Typha; in North America, Cyperus virens is the only reported secondary host. Activity peaks in spring and autumn on primary hosts.
Dentifibula viburni
Dentifibula viburni is a gall midge species (Diptera: Cecidomyiidae) originally described by Felt in 1907 as Contarinia viburni. The species is associated with Viburnum host plants, as indicated by its specific epithet. It belongs to the subfamily Cecidomyiinae, a group known for inducing plant galls. Very little published information exists regarding the biology, distribution, or economic significance of this particular species beyond its taxonomic description and nomenclatural history.
Enchenopa on-viburnum-nudum
Enchenopa on-viburnum-nudum is a treehopper species in the family Membracidae, tribe Membracini. The specific epithet indicates a host association with Viburnum nudum (possumhaw or smooth witherod). Members of the genus Enchenopa are characterized by their distinctive pronotal crests and treehopper morphology. Like other Enchenopa species, this taxon likely exhibits host plant specificity typical of the genus.
Enchenopa on-viburnum-prunifolium
Enchenopa on-viburnum-prunifolium is a treehopper species in the family Membracidae. The specific epithet indicates an association with Viburnum prunifolium (blackhaw viburnum), suggesting host plant specificity. Treehoppers in the genus Enchenopa are characterized by their distinctive pronotal crests and are predominantly Neotropical in distribution, though some species occur in North America.
Enchenopa on-viburnum-rufidulum
Enchenopa on-viburnum-rufidulum is a treehopper species in the family Membracidae, documented as a host-specialist on Viburnum rufidulum (rusty blackhaw). This species represents part of a complex of Enchenopa host-races that have diversified on different plant lineages. The specific epithet reflects its documented association with this particular Viburnum host. Host-race formation in this group has been studied as a potential case of incipient speciation driven by host plant shifts.
Gnorimella
maculate flower scarab
Gnorimella is a monotypic genus of scarab beetles in the family Scarabaeidae, containing the single species Gnorimella maculosa. This uncommon beetle is notable for its spotted patterning and association with deciduous woodland habitats in eastern North America. The genus was established by Casey in 1915 and remains one of the more rarely encountered cetoniine scarabs in its range.
Marmara viburnella
Marmara viburnella is a micro-moth in the family Gracillariidae, subfamily Phyllocnistinae. It is a leaf-mining species whose larvae create serpentine mines in host plant foliage. The species is known from northeastern North America, with records from Canada (Quebec) and the United States (Connecticut, Illinois, Louisiana, Maryland). As a member of the genus Marmara, it exhibits the highly reduced wing venation and elongated body form characteristic of this group of minute moths.
Pamphilius ochreipes
Viburnum Web-spinning Sawfly
Pamphilius ochreipes is a web-spinning sawfly in the family Pamphiliidae. Larvae feed within leaf rolls on cultivated Viburnum opulus, constructing silk webbing for protection. The species has a univoltine life cycle, overwintering as larvae in soil and emerging as adults in late spring. Adults have been collected across North America, though detailed biological studies are limited to southern Ontario populations.
Pyrrhalta viburni
Viburnum leaf beetle
Pyrrhalta viburni, the viburnum leaf beetle, is a Eurasian leaf beetle (Chrysomelidae) that has become a significant invasive pest in North America. Native to Europe and Asia, it was first detected in Canada in 1947 and spread to the northeastern United States by 1996. The beetle is a specialist herbivore of Viburnum shrubs, with both larvae and adults feeding on foliage. Severe infestations can completely defoliate host plants, leading to plant decline or death. The species exhibits distinctive aggregative oviposition behavior, with females preferentially laying eggs on twigs already containing conspecific egg masses.
