Caliscelis is a of planthoppers in the Caliscelidae, established by Laporte in 1833. These insects belong to the infraorder Fulgoromorpha, a group of true bugs known for their distinctive and jumping hind legs. The genus is part of the tribe Caliscelini within the Caliscelinae. Members of this genus are found primarily in the Palearctic region, with documented observations across Europe and parts of Asia.
Identification
Caliscelis can be distinguished from other caliscelid by their characteristic structure, which is typically produced into a distinct process or projection anteriorly. The forewings are usually shortened, exposing part of the , a trait common in Caliscelidae but with genus-specific proportions. The overall body form is compact and somewhat flattened dorsoventrally. Species-level identification requires examination of genitalia and detailed head .

Habitat
in this inhabit grassland and meadow , particularly in areas with dense herbaceous vegetation. They are associated with grasses and sedges in both dry and mesic conditions. include steppe, prairie margins, and unmanaged grasslands with low to moderate disturbance.
Distribution
Palearctic distribution, with records from Europe (including France, Spain, Italy, Central Europe, and Eastern Europe) and extending into Central Asia. The appears to be most diverse in the western Palearctic, with some reaching into the eastern Mediterranean and Caucasus regions.
Seasonality
are active during the warmer months, with peak activity from late spring through summer (May–August in temperate regions). Nymphs likely overwinter in grass root zones or leaf litter, with development resuming in spring.
Ecological Role
As phloem-feeding insects, members of this participate in nutrient cycling within grassland . They serve as prey for various and may contribute to the diet of insectivorous birds and small mammals. Their -specific relationships with grasses potentially influence plant dynamics, though quantitative effects remain unstudied.
Human Relevance
No direct economic importance. The is of interest to hemipteran systematists and biodiversity researchers documenting grassland insect . Some may serve as indicators of semi-natural grassland quality.
Similar Taxa
- BruchomorphaAlso in Caliscelidae with shortened forewings, but Bruchomorpha have a more strongly produced, often process and different wing venation patterns.
- OmmatidiotusShares characteristics but differs in shape, which is less produced anteriorly, and in the structure of the male genitalia.
- AphelonemaNorth American caliscelid with superficially similar body form; distinguished by geographic range and details of the capsule and wing shape.

Taxonomic history
The has undergone several revisions, with boundaries historically confused due to morphological convergence. Modern treatments rely on male genitalic structures for definitive species identification.
Conservation status
Several European have experienced range contractions due to agricultural intensification and loss of semi-natural grasslands. They are occasionally included in regional red lists, though -wide assessments are lacking.
