Citrine Forktail damselfly (male)

June 28, 2018

A Citrine Forktail damselfly (Ischnura hastata) was spotted during a stream-walk along South Fork Quantico Creek in Prince William Forest Park (PWFP), Prince William County, Virginia USA. This individual is a male, as indicated by his coloration and terminal appendages.

Citrine Forktail is the smallest species of damselfly in North America. Maybe that explains why it took so long to add Citrine to my life list of odonates!

Every reference I have read says Citrine habitat is lentic, that is, it prefers ponds and lakes rather than the lotic habit where I found the individual shown above. I wish I had carried one of my camera kits for macro photography, but I didn’t expect to see Citrine along a mid-size stream.

Lentic and lotic

October 3, 2017

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.”
