Euschistus tristigmus
Dusky Stink Bug
Euschistus tristigmus, commonly known as the dusky stink bug, is a pentatomid species native to North and Central America. It belongs to the economically important genus Euschistus, which includes several brown stink bug species that are agricultural pests. The species exhibits adult seasonal dimorphism, with morphological differences between spring and summer generations. Research has documented its vertical distribution patterns in pecan orchards, where it shows a preference for canopy habitats compared to the ground-dwelling tendencies of its congener Euschistus servus.
