Baby bugs (nymphs) are initially bright green as are the eggs from which they hatch, before turning orange-red with a black dot on their back. An adult is bronzy-black with a broad thick body and a triangular back plate. Its head is small in relation to the rest of its body and it has orange antennae and leg joints.
Eggs are about 2.5 mm in diameter; adults are about 2.5 cm long.

After mating, females lay eggs on the underside of host leaves, and the bright green eggs hatch into baby bugs (nymphs) about one week later.
