Three or four key characteristics are used to distinguish the brown marmorated stink bug (BMSB) from other stink bugs found in the Pacific Northwest: 1) white bands on the brown antennae, 2) bands on the dorsal (top) side of the peripheral margin of the abdomen, 3) smooth leading edge of the prothorax (shoulders), 4) ‘gem-encrusted’ prothorax just behind the head (on both the dorsal and ventral side).
