The Celithemis eponina, commonly known as the Halloween Pennant, is a striking dragonfly species found in North America, particularly in the eastern United States. It is easily recognizable by its colorful, patterned wings that resemble the colors of Halloween—orange, black, and yellow—with a distinctive dark line running across the wings. Halloween Pennants inhabit wetlands, ponds, and marshes, where they are often seen perched on vegetation or flying in search of prey. They are known for their territorial behavior and aggressive nature, making them fascinating to observe. The larvae are aquatic, and the adults play a role in controlling mosquito populations.
