Libellula quadrimaculata, most commonly known as the Four-Spotted Chaser. This common name of a "chaser" originates from the organism's tendencies; if any organism or any other dragonfly is near its territory, it will viciously chase them away. It is called the "four-spotted" chaser because of the dark spots on each of its wings - there are commonly two spots on each wing, totalling four on each side of the body.
