Blue-faced Meadowhawk mating frenzy

Old Colchester Park and Preserve (OCPP), Fairfax County, Virginia USA is one of a few places in Northern Virginia where Blue-faced Meadowhawk dragonfly (Sympetrum ambiguum) is known to occur. OCPP is located near Mason Neck West Park.

More than ten mating pairs of Blue-faced Meadowhawks were spotted at a small vernal pool in the park; the pool was almost completely dry on the day of my visit.

Andromorph females

Some species of dragonflies, such as Blue-faced Meadowhawk, display sexual dimorphism; females are polymorphic for a smaller subset of those species. Andromorph females are male-like in color; heteromorph females are duller in color than males.

Andromorph female Blue-faced Meadowhawk dragonflies, like the ones shown below, are less common than heteromorph females. Andromorphs have a red abdomen with black rings, like male Blue-faced Meadowhawks; unlike males, most female faces are tan and their terminal appendages look different than male appendages.
