Javesella discolor
Family: Delphacidae

Javesella species occur as both macropterous and brachypterous forms, and show a variety of colouration; identifications must be made with care, and separation of species is not always possible from photos.

J. discolor has generally shorter wings than J. dubia or J. pellucida (allthough macropters do occur), typically very dark brown and with a white apical edge. The male genital segment is convex posteriorly in side view. The scutellum also typically has a pale apex.

Found in long grass in a variety of places, including woods and open, high-altitude moorland. Widespread across the UK.

Adult: April to November
Length 2.5-4 mm
