Final Fine-lined Emerald

October 7, 2019

Several Fine-lined Emerald dragonflies (Somatochlora filosa) were spotted during a photowalk with Michael Powell at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA. At least six S. filosa were spotted along two dirt/gravel roads at the refuge; this is the last one we saw.

This individual is a male, as indicated by his “indented” hind wings and terminal appendages.

Decisions, decisions!

I shot 37 photographs of the following dragonfly perched in several places: two photos are out of focus; most of the rest are flawed in some way (in my opinion), for example I don’t like the background, or the composition, etc.

As it turns out, the last group of photos is my favorite. Within that group, I selected a subset of three photos that I like. Although the photos are similar, they are subtly different. I think one of the images is the clear winner, but I suffer from decision paralysis sometimes. The photos are shown in the order in which they were taken. Which one is your favorite?

Sidestory

I think I might have figured out the habitat/breeding habitat for Fine-lined Emerald dragonflies. As Mike Powell and I were walking along one of several roads at Occoquan Bay NWR that lead to hotspots for hunting Fine-lined Emerald, I noticed shallow pools of “black water” in the forest, beginning about halfway down one of the dirt/gravel roads at the park. I mentioned to Mike that I think the black water pools are habitat for S. filosa.

Sure enough, that’s exactly where we spotted the male featured in this post — the last one we saw as we were walking back to Mike’s car. It’s worth noting we have never seen a Fine-lined Emerald that far from the main hotspots. Mike saw several more S. filosa in the same area a few days later. Hey, I might be onto something!

Yet another male Fine-lined Emerald

September 30, 2019

The following images show the third Fine-lined Emerald dragonfly (Somatochlora filosa) that I photographed during a photowalk on 18 September 2019 at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

This individual is a male, as indicated by his “indented” hind wings and terminal appendages. The following photo shows both field marks clearly.

Personality

Do dragonflies have personality? Who knows? I’ll say this: Some individuals within the same species seem to behave in ways that are distinctly observable and slightly atypical.

For example, this guy was hyperactive. He flew from perch-to-perch as though he were searching for the perfect perch. After brief stops at several spots, he disappeared into the tree canopy.

Before Mike Powell and I spotted the male featured in this post, we watched another male patrol back-and-forth between us for more than 30 minutes without landing! Mike and I were standing along a dirt/gravel road, about 20-30 yards apart. We had a lot of fun “redirecting” the dragonfly in the opposite direction toward each other. Several times the dragonfly “pulled up” in front of me and appeared to be thinking about landing on my head, but we were never so lucky. Eventually, the male must have tired of the game because he simply vanished!

Perhaps I’m guilty of personification of dragonflies, but I think they have lots of personality!

Another male Fine-lined Emerald

September 25, 2019

The following gallery shows the second Fine-lined Emerald dragonfly (Somatochlora filosa) that I photographed during a photowalk on 18 September 2019 at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

This individual is a male, as indicated by his “indented” hind wings and terminal appendages. The following photo shows both field marks clearly.

Male Fine-lined Emerald dragonflies typically patrol back-and-forth along relatively short segments, about waist high; in this case, they were patrolling along dirt/gravel roads in the forest. They perch about head high on tall grasses or bare tree branches.

Fine-lined Emerald dragonfly (male)

September 20, 2019

A Fine-lined Emerald dragonfly (Somatochlora filosa) was spotted during a photowalk at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA. Several specimens were spotted along two dirt/gravel roads at the refuge; this is the first one I saw.

This individual is a male, as indicated by his “indented” hind wings and terminal appendages.

Adult Flight Period

According to records for the Commonwealth of Virginia maintained by Dr. Steve Roble, Staff Zoologist at the Virginia Department of Conservation and Recreation, Division of Natural Heritage, the adult flight period for S. filosa is from July 10 to October 15. The species is classified as rare to uncommon. Its habitat is “boggy streams, swamps, and marshes.”

Bear in mind, Dr. Roble’s records are for the entire state, therefore the adult flight period for S. filosa seems to be longer than it is in reality. The adult flight period for a single site is probably shorter. For example, according to records for Northern Virginia maintained by Kevin Munroe, former manager of Huntley Meadows Park, the adult flight period for Fine-lined Emerald is August 23 to October 04.

Rare to Uncommon

A distribution map of official records for Fine-lined Emerald helps to illustrate its classification as a rare to uncommon species of odonate.

After the boys of summer are gone.

September 18, 2019

An Eastern Amberwing dragonfly (Perithemis tenera) was observed during a photowalk with Michael Powell at Painted Turtle Pond, Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

16 AUG 2019 | Occoquan Bay NWR | Eastern Amberwing (male)

This individual is a male, as indicated by his orange coloration and terminal appendages.

Eastern Amberwing is one of the “boys of summer.” By mid-September, the transition from the summer species of odonates to fall species is well underway.

Calico Pennant dragonfly (male)

September 6, 2019

There’s a feeling I get
When I look to the west
And my spirit is crying for leaving.

A Calico Pennant dragonfly (Celithemis elisa) was observed during a photowalk with Michael Powell at Painted Turtle Pond, Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

This individual is a mature male, as indicated by his red coloration, the secondary genitalia (hamules) located on the underside of abdominal segments two-three (2-3), and terminal appendages.

Blue-ringed Dancer damselfly (male)

September 2, 2019

A Blue-ringed Dancer damselfly (Argia sedula) was spotted during a photowalk with Michael Powell along Popes Head Creek at Hemlock Overlook Regional Park (HORP), Fairfax County, Virginia USA.

29 AUG 2019 | HORP | Blue-ringed Dancer (male)

This individual is a male, as indicated by his blue coloration and terminal appendages. (Female Blue-ringed Dancer is mostly brown/tan in color.)

29 AUG 2019 | HORP | Blue-ringed Dancer (male)

Adult flight period

According to records for the Commonwealth of Virginia maintained by Dr. Steve Roble, Staff Zoologist at the Virginia Department of Conservation and Recreation, Division of Natural Heritage, the adult flight period for A. sedula is from May 17 to October 24. The species is classified as common. Its habitat is “streams” and “rivers.”

Bear in mind, Dr. Roble’s records are for the entire state, therefore the adult flight period for A. sedula seems to be longer than it is in reality. The adult flight period for a single site is probably shorter.

New species

Blue-ringed Dancer is a new species for my Life List of Damselflies (Order Zygoptera).

Fawn Darner dragonfly (male)

August 26, 2019

A Fawn Darner dragonfly (Boyeria vinosa) was spotted, netted, and released unharmed along the Little Patuxent River in the North Tract of Patuxent Research Refuge, Anne Arundel County, Maryland USA.

02 SEP 2012 | Patuxent Research Refuge | Fawn Darner (male)

This individual is a male, as indicated by the secondary genitalia (hamules) located on the underside of abdominal segments two-three (2-3).

02 SEP 2012 | Patuxent Research Refuge | Fawn Darner (male)

Thanks to Louisa Craven, my good friend and photowalking buddy, for holding the specimen in the first two photos while I used her Apple iPhone 4S to take photos. This was our first “stream walk” in search of dragonflies and damselflies and both of us were afraid to carry our camera gear as we waded in the river.

02 SEP 2012 | Patuxent Research Refuge | Fawn Darner (male)

The Backstory

I posted these photos in my Project Noah Nature Journal two days after an Audubon Naturalist Society field trip to the North Tract of the Patuxent Research Refuge, led by Richard Orr, renowned expert on odonates of the mid-Atlantic region of the United States.

Some of the photos from the Project Noah “spotting” were added to my photoblog in order to backfill my Life List of Odonates to include a record of an adult Fawn Darner.

“Grays” love them some me!

August 14, 2019

2019 was a record-setting year for observing Gray Petaltail dragonflies (Tachopteryx thoreyi) with Mike Powell at an undisclosed location in Prince William County, Virginia USA.

  • 21 May 2019 was the day that we observed at least a dozen (12+) Gray Petaltail — the most on any day during 2019.
  • 14 June 2019 was the day that the most “Grays” landed on me, including one female and two males plus some others that didn’t perch long enough to be photographed by either Mike or me.

Female

The first individual is a female, as indicated by her rounded hind wings and terminal appendages. She is perched on the front of my gray-green shirt.

Please get this man to a barber STAT! On the other hand, there isn’t much else that can be done about the face. As you can see, I’m the owner of a high mileage “vehicle” — fortunately it still runs good!

Males

The next individual is a male, as indicated by his “indented” hind wings, and terminal appendages. He is perched on the right sleeve of my shirt.

Photo used with permission from Mike Powell.

The same male is shown in the following image. This photo is my favorite in the gallery.

The last individual, possibly/probably a male, is perched on my off-white bucket hat. The “Gray” was doing a Vulcan mind-meld with me by using specialized contact via the tips of his legs.

Eastern Ringtail reunion, continued

August 5, 2019

Whenever possible I prefer to photograph odonates against a clean background, such as the concrete pavement in my last blog post. In my opinion, a simpler background makes it easier for the viewer to focus on the subject.

In contrast, my photowalking buddy Mike Powell prefers a “natural” background (as opposed to man-made). Knowing Mike’s preference, I “influenced” an Eastern Ringtail (Erpetogomphus designatus) to relocate from his perch on a concrete sidewalk to a new perch on a grass lawn. Although the green grass complements the unusual color palette of the dragonfly, the viewer’s eye must work harder to find the subject.

This individual is a male, as indicated by his “indented” hind wings, and terminal appendages. He is perched on a grassy area in between concrete sidewalks surrounding a berm/observation area alongside the boat ramp, near the main parking lot at Riverbend Park.

Adult flight period

According to records for the Commonwealth of Virginia maintained by Dr. Steve Roble, Staff Zoologist at the Virginia Department of Conservation and Recreation, Division of Natural Heritage, the adult flight period for E. designatus is from May 16 to September 24. The species is classified as uncommon to common. Its habitat is “rivers.”

Bear in mind, Dr. Roble’s records are for the entire state, therefore the adult flight period for E. designatus seems to be longer than it is in reality. The adult flight period for a single site is probably shorter. For example, according to records for Northern Virginia maintained by Kevin Munroe, former manager of Huntley Meadows Park, the adult flight period for Eastern Ringtail is 09 June to 20 September.
