Bronze orange bugs are shield/ stink bugs. The adults are quite large, oval-shaped and dark bronze in colour with a triangular shaped plate on their back.
The nymphs are pale green when first hatched, changing colour with each instar (grey-green, yellow, pinky-orange, and dark brown). They are very flat and have a black spot on their backs.
The eggs and hatchlings are both very hard to see as they are well camouflaged blending in with the colour of the leaves.
They are strong flyers but slow moving. Like other stink bugs they excrete a foul-smelling liquid as a defensive response when disturbed. This liquid stains and can burn skin.
Adult size: 25mm
