Length 3 mm. Javesella species occur in both long winged and short winged forms and show a variety of colouration; identifications must be made with care and the separation of species is not always possible from photos. Males are much darker than females, and the fully winged forms of both are generally darker than the short winged. The translucent forewings are normally slightly brownish or whitish.
Adult: April to October.
Grasses are the main foodplants but certain conifers and horsetails also used. Short winged forms are more commonly found in low-nutrient sites.
This widespread species is one of the most common UK delphacids.
Fairly frequent in Leicestershire and Rutland.
