Widespread north to Edinburgh (Musgrove, 2023).
This species is mainly parthenogenic with males being rare. The hind femur is red in contrast to the black and white hind tibiae. The front femora and tibiae are at least dark in part. The female has a white scutellum and white flecks on the lateral faces of the abdomen, but the rare males are black on those parts. Adults feed by scraping the leaves of the larval food plants and eating the resultant pulp.
Larvae feed Wild Privet (seemingly not the garden varieties), Lilacs and Common Ash. Eonymphs can move around in leaf litter for up to six weeks before burrowing.
