Rough stink bugs (Brochymena sp.) are native predators of soft-bodied insects, which are often confused with the non-native, plant-feeding Brown Marmorated Stink Bugs (Halyomorpha halys,). Rough stink bugs have two white bands on their hind legs and have no bands on their antennae. They also have a toothed margin on the front of the thorax ("shoulders"), from which they get their common name. Brown marmorated stink bugs have white bands on the antennae, and relatively smooth shoulders.
Adults of rough stink bug, Brochymena sulcata (left), a beneficial predator compared with brown marmorated stink bug, Halyomorpha halys, a plant-feeding pest. Rough stink bugs have two white bands on the hind legs, no bands on their antennae, points on the face, and a rough or toothed edge on top the thorax (or "shoulders"). Adults of brown marmorated stink bug have one white band on their hind legs, white bands on the antennae, a blunt face, and relatively smooth shoulders.
Rough stink bugs overwinter as adults under loose bark or in other crevices, but occasionally find their way into houses. They are difficult to identify to species without examining them with a microscope.
