It was a Libby Lula Hula Hoopy day doing playground duty in the late afternoon. What looked like bright yellow tiny Libby and Lulawere playing tag around my ankles in the sun-soaked grass. These weren't yellowjackets, though. I kept my eyes on the children, but also on these vivid yellow flying insects. Eastern Amberwing Perithemis tenera: Libellulidae seems to be our new playground friend. Perithemis tenera sounds like a psychosomatic illness related to writing final exam essays in Blue Books, but "Amberwing" sounds gentle, wise, and tolerant in a British way. Odonata Central helped me solve my mystery of these delightful dragonflies.
