Tropical Pennants
Brachymesia is a genus of dragonflies in the family Libellulidae, commonly known as tropical pennants. The genus contains multiple species distributed across the Americas, with B. gravida restricted to the United States and other species occurring throughout South America, the West Indies, and southern USA states. One species, B. herbida, has been studied in insular populations where it exhibits distinct behavioral patterns compared to sympatric libellulids.
