Needham’s Skimmer dragonfly (male) redux

The following photo shows a Needham’s Skimmer dragonfly (Libellula needhami) perched on a branch of a small tree that had fallen in the Paul Spring stream bed. This individual is a male, as indicated by its coloration and the “claspers” (terminal appendages) at the end of its abdomen.

Look closely at the dragonfly’s compound eyes. Notice the darker colored areas called “pseudopupils.” According to Richard Orr, renowned expert on dragonflies and damselflies of the mid-Atlantic region, pseudopupils indicate areas of higher visual acuity.
 Habitat: “Paul Spring Park,” one of seven small parks owned and maintained by the Community Association of Hollin Hills, Fairfax County, Virginia USA. Paul Spring is a small year-round stream that flows through Paul Spring Park.
