|Adult of Orientus ishidae|
The adults reach 4.5–6.5 millimetres (0.18–0.26 in) of length. This leafhopper shows a distinctive mosaic-like pattern on the forewings and an orange band between the eyes. Orientus ishidae is associated with willow (Salix species), hornbeam (Carpinus betulus) and with many woody plants and deciduous trees. It may cause serious leaf damages to several tree species and is implicated as a vector of the phytoplasmic flavescence dorée (FD) disease in vineyards. Adults can be found from June to October.
The nymphs are strongly coloured, the patterning is variable. They often adopt a tail-up posture in response to danger, as seen on the left.
This species is endemic to the East Palearctic ecozone and it is present in the Nearctic ecozone and in the Oriental ecozone. It has been introduced in United Kingdom (first reported in Peckham, 2011), Germany, Italy, Switzerland and in several other European countries.
