(Pachydiplax longipennis). This common dragonfly is also one of the most approachable. Often sitting on the tip of a cattail leave, their wings are held in a “set wing” position. down and forward for quick takeoffs. Key fieldmarks: yellow stripes on sides of thorax, turquiose eyes, white face with black “nose” between eyes, blue abdomen. Habitat: ponds, gentle streams. Season: all summer. Photo by Scott Severs.
