Eurybregma nigrolineata
Family: Delphacidae

 An extremely distinctive species with bold black stripes (partly brown in females) on the dorsal surface and forewings. The facial markings include at least lateral longitudinal stripes on the lower part of the frons, and sometimes these are continuous with spots on the vertex.  Both brachypters and macropters occur; the wing stripes are less clear in the latter. Difficult to confuse with other UK delphacids, although Eurysa lineata also has longitudinal markings.

 Mostly in southern England, and relatively local. Occurs on grassy both in marshes (especially saltmarshes) and in grassy habitats inland.
Adult: May to July
Length 3-5 mm
