A member of the Somatochlora genus, otherwise known as the "striped emeralds." (1) Both yellow thoracic side stripes are small, nearly-circular ovals. (2) The abdomen is disproportionately SHORT and lacks distinctive pale spots. (3) Male claspers are ski-shaped and almost meet in center from top view, whereas the female ovipositor is long, triangular, T-type (perpendicular to length of abdomen). No other Somatochloran has this combination of features. This is among the most common striped emeralds in Wisconsin, particularly at slow forest streams outside of the southernmost counties in the state.
