Triacanthagyna septima, commonly known as the pale green darner, is a relatively small aeshnid dragonfly found across the Americas from the southern United States through Central America to South America. Adults measure 59–66 mm in length with a wingspan of 68–86 mm. The species exhibits subtle sexual dimorphism, with females possessing three long, slender cerci that may break off in mature individuals, causing them to resemble males.
