Arge pagana
One of the yellow and black species. The pronotum, tegulae and parts of the legs are suffused with black. Wings more or less smoky.
The variation in the degree of dark markings gives two subspecies in Britain. The paler stephensii form has more extensive yellowing on the labrum, middle and hind coxae, femora and tibiae and sometimes upper mesopleural parts, pronotum and mesonotal lobes. The darker pagana form has head, thorax and legs entirely black. It is suspected that the two forms maybe separate species but further study is required.
Larvae feed on roses.
Status: Locally common
