Doesn’t this idyllic place look like ideal habitat for lotic species of odonates? It is!

Lotic refers to flowing water, from the Latin lotus, washed. … Lotic ecosystems can be contrasted with lentic ecosystems, which involve relatively still terrestrial waters such as lakes and ponds. Source Credit: River ecosystem, Wikipedia.
The preceding photo shows the stream crossing at Popes Head Creek, Hemlock Overlook Regional Park, Fairfax County, Virginia USA (facing downstream toward Bull Run). Both streams provide ideal habitat for many species of dragonflies and damselflies that prefer flowing water rather than still water.
Tech Tip: I used my Panasonic Lumix DMC-FZ150 superzoom camera to shoot the landscape photo featured in this blog post. The camera was set for manual focus at the hyperfocal distance for an aperture of f/4, based upon the instructions provided in the excellent video tutorial by Graham Houghton, “Panasonic Lumix FZ camera easier manual focus method — super point-and-shoot tip.”
