Brown marmorated stink bug adult is a typically-shaped stink bug having marbled brown colour.
Characteristics:
Eggs: The eggs of the brown marmorated stink bug are a light green or light blue color, 1 mm in diameter, and are laid in clutches of approximately 28 eggs. Eggs are usually located on the underside of leaves of host plants. As the embryo develops it may become visible through the egg, with the eyes appearing as two red spots.
Adult: They have marbled brown head and thorax and reddish brown, black, and white abdomen markings. They have distinct white bands on the antennae and legs and spines in front of red eyes and on shoulder edges. They have patches of coppery or bluish-metallic colored puntures (small rounded depressions) on the head and pronotum. When disturbed or squashed, the stink bugs release an unpleasant odor from scent glands on their abdomen.
The presence of this stink bug is concerning for farmers because it feeds on a large number of high-value crops in its immature and adult life stages.
