Identification
Chloriona can be distinguished from other delphacid by the combination of: a greenish or glaucous body coloration (evident in species epithets such as glaucescens and smaragdula); forewings with reduced venation; and male genitalia with distinctive paramere structure. The genus is characterized by a slender, elongate body form compared to some more robust delphacids. Accurate species-level identification requires examination of male terminalia and is beyond field identification for most observers.
Habitat
of Chloriona inhabit grass-dominated environments including meadows, marshes, and the margins of wetlands. They are associated with Poaceae (true grasses), their presumed plants. Specific microhabitat preferences vary by species, with some occupying drier calcareous grasslands and others restricted to wetter fen or bog margins.
Distribution
The occurs across Eurasia. Distribution records include Germany (DE), Denmark (DK), Norway (NO), and Sweden (SE), with the genus as a whole ranging more broadly across Europe and into Asia. Individual show more restricted ranges; for example, Chloriona vasconica occurs in the western Pyrenees region.
Host Associations
- Poaceae - probable plantInferred from -level ; specific records for Chloriona are not well documented
Ecological Role
As phloem-feeding herbivores, Chloriona function as primary consumers in grassland . They serve as prey for various including spiders, predatory insects, and birds. Their may reflect quality in undisturbed grassland .
Human Relevance
Chloriona have no documented economic importance as agricultural pests or beneficial insects. The may serve as an indicator of semi-natural grassland quality in conservation monitoring.
Similar Taxa
- JavesellaBoth are greenish delphacid in similar ; Javesella generally show more contrasting dark markings on the and pronotum, and differ in male genitalia structure.
- KelisiaKelisia are smaller, more compact delphacids with reduced wings in some species; Chloriona are larger, more elongate, and fully winged.
- StenocranusStenocranus share the elongate body form but typically have more pronounced dark patterning on the wings and different shape; male genitalia provide definitive separation.

Species diversity
The contains five recognized : Chloriona chinai, Chloriona glaucescens, Chloriona smaragdula, Chloriona stenoptera, and Chloriona vasconica. Chloriona smaragdula is the most widespread and frequently recorded species in northern Europe.
Taxonomic history
The was established by Franz Xaver Fieber in 1866 in his work on European Hemiptera. The name Chloriona derives from Greek chloros (green) and likely refers to the characteristic coloration of these planthoppers.
