Although there are over 200 species of stink bugs in North America, some are relatively easy to identify. Many bear the dull brownish appearance of the individual shown here, but only the dusky stink bug (Hemiptera: Pentatomidae: Euschistus tristigmus) features three prominent black spots down the ventral midline of the abdomen.
These true bugs can be found in forests and meadows in southern Canada and the northern United States. They use their piercing-sucking mouthparts to feed on the fluids of a wide variety of trees, shrubs, and herbaceous plants.
These insects overwinter as adults, and in the twilight of summer this individual was likely looking for some comfortable leaf litter to snuggle up in.
