The following photographs show an Eastern Pondhawk dragonfly (Erythemis simplicicollis) spotted on the earthen dam at Hidden Pond, Meadowood Recreation Area, Fairfax County, Virginia USA. This individual is an immature male, as indicated by its green coloration and terminal appendages.
The following gallery features a couple of similar-looking dragonflies: they are the same species; different gender. Both specimens are Common Whitetail dragonflies (Plathemis lydia): Photo 1 shows an immature male; Photos 2-3 show a female. Notice the obvious difference in the pattern of their wing spots. More careful observation reveals the difference in their terminal appendages.
Photo 1: Immature male.
Photo 2: Female.

Young males begin to develop pruinescence that changes the color of their abdomen from brown to white.
The following slideshow features a time-series of six photos showing the snapping turtle blowing bubbles in the water. Do turtles play? (I liked to use a drinking straw to blow bubbles in a glass of milk when I was a child.)
The following gallery shows a few male Blue Corporal dragonflies (Ladona deplanata) perching on me as I was standing on the earthen dam at Hidden Pond, Meadowood Recreation Area, Fairfax County, Virginia USA. The natives are very friendly!

The following photos show a Spangled Skimmer dragonfly (Libellula cyanea) spotted in an open field along the trail to Hidden Pond, a small lake located at Meadowood Recreation Area in Fairfax County, Virginia USA. This individual is an immature male, as indicated by its coloration and the terminal appendages at the end of its abdomen.
The following photographs show a Stream Cruiser dragonfly (Didymops transversa) spotted along “Beaver Pond Loop Trail” at Accotink Bay Wildlife Refuge, a 1,200 acre preserve located at Army Garrison Fort Belvoir, Fairfax County, Virginia USA. This individual is a male as indicated by the white terminal appendages at the end of its abdomen. The abdomen of male Stream Cruisers is enlarged near the tip, similar to the Clubtail family of dragonflies.
Dragonflies breathe through small holes in the underside of their thorax and abdomen called “spiracles.” Notice the dragonfly’s thorax and abdomen expanding and contracting as he inhales and exhales.
