Two species of teneral dragonflies were spotted on the same day at nearly the same location in Huntley Meadows Park.
teneral: adult after it has just emerged, soft and not definitively colored Source Credit: Glossary, Some Dragonfly Terms by Dennis R. Paulson.
Both species are members of the Family Libellulidae (Skimmers). Based upon my experience, early September seems late in the year for these two species to emerge!
