An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

The rape bug has a shiny, flat dark-colored body about 5–7 millimetres (0.20–0.28 in) long and 4 millimetres (0.16 in) wide. The species has a dark ground colour which is overlain with red, yellow, cream, white or orange markings. There is an oval spot on the top of the mesonotum and one on each of the elytra as well as a longitudinal stripe on the prothorax. In young adults these spots are yellow but change to white or red in older bugs. The colour of the abdomen changes at the same time from buff to black. Such age-specific changes in the imago coloration, are connected with sexual maturation of the bugs and often take place in diapausing imagos at the time they are becoming active again.[2]

  • The rape bug has a shiny, flat dark-colored body about 5–7 millimetres (0.20–0.28 in) long and 4 millimetres (0.16 in) wide. The species has a dark ground colour which is overlain with red, yellow, cream, white or orange markings. There is an oval spot on the top of the mesonotum and one on each of the elytra as well as a longitudinal stripe on the prothorax. In young adults these spots are yellow but change to white or red in older bugs. The colour of the abdomen changes at the same time from buff to black. Such age-specific changes in the imago coloration, are connected with sexual maturation of the bugs and often take place in diapausing imagos at the time they are becoming active again.[2] The eggs are cylindrical, buff colored with a dark pattern. They are laid on the stems and inflorescences of host plants in batches usually of about twelve eggs in two neat rows. Each female lays sixty to eighty eggs over a period of four to six weeks. The nymph is pale gray with a dark brown pronotum and spots on the dorsal side of the abdomen. It moults five times and the adults and nymphs live quite openly on plants. Adults overwinter, hibernating in leaf debris at the edge of woods or in bushes.
