Ribautodelphax albostriata
(Fieber, 1866)
Ribautodelphax albostriata is a of planthopper in the Delphacidae, first described by Fieber in 1866. It is a small, grass-feeding insect with a trans-Palearctic distribution, recorded from Europe through Central Asia to North America. The species is among the more frequently observed members of its , with documented occurrences in diverse grassland .

Identification
Distinguished from by the combination of pale coloration with prominent white stripes and the structure of the male genitalia (critical for definitive identification). The and parameres require microscopic examination for -level determination. Separated from superficially similar delphacids by the relatively broad vertex and the pattern of white striping, which is more pronounced than in most Ribautodelphax species. R. albostriata lacks the darker markings present in R. pungens and R. notabilis.
Images
Appearance
Small planthopper, approximately 3-4 mm in length. Body generally pale with distinctive white longitudinal stripes on the surface, corresponding to the epithet 'albostriata' (white-striped). Wings membranous, held roof-like over the body at rest. Hind tibiae bear characteristic mobile spurs, a -level trait. Vertex of relatively broad, with carina.
Habitat
Grassland including meadows, pastures, and marshy areas. Associated with Poaceae (grasses) in both wet and dry conditions. Recorded from lowland to montane elevations.
Distribution
Trans-Palearctic distribution. Documented from Europe (including Italy: Abruzzo), Central Asia (Kazakhstan: Almaty, Altay), and North America (Alaska, Alberta, Canada). The North American records may represent introduced or reflect broader Holarctic range.
Seasonality
active from late spring through summer; precise varies by latitude.
Diet
Phloem-feeding on grasses (Poaceae). Specific grass have not been documented.
Ecological Role
Herbivore in grassland ; serves as prey for various including spiders, predatory insects, and birds.
Human Relevance
No documented economic importance. Occasionally encountered in agricultural grasslands but not reported as a pest.

Taxonomic note
The Ribautodelphax was established to accommodate previously placed in Delphacodes and related genera, based on differences in male genitalia and wing venation. R. albostriata is the type species of the genus.
