It’s fun to remember the carefree days earlier this year that I spent hunting for dragonflies. Fellow dragonfly enthusiast Walter Sanford recently did a posting about a location where I photographed a Sable Clubtail dragonfly, one of the rarest species in our area, a place that he christened “Powell’s Place” after he too visited it and found a Sable Clubtail.

Be sure to check out his posting and I encourage you also to explore his blog for some amazing photos and information about dragonflies and other wild creatures.

A single Sable Clubtail dragonfly (Stenogomphurus rogersi) was spotted perched alongside a small stream located in Fairfax County, Virginia USA.

I nicknamed a segment of the stream “Powell’s Place” in honor of Mike Powell, my good friend and photowalking buddy, who spotted the first Sable observed at this part of the stream. “Powell’s Place” is located downstream from Hotspot No. 1, where the stream re-emerges from an underground concrete pipe.

This individual is a male, as indicated by his indented hind wings and terminal appendages. Some dragonflies tend to be creatures of habit, returning to the same spot day-after-day. Perhaps this is the same individual spotted by Mike. Who knows?

I like the juxtaposition of complementary colors in the first photo.

I love dragonflies, but it will probably be a month or two before they reappear in my area. I bide my time and photograph birds during the winter, but one of my fellow dragonfly enthusiasts, Walter Sanford, has been spending his time studying exuviae, the exoskeletons that are discarded when nymphs almost magically undergo a metamorphosis and emerge as dragonflies. Check out Walter’s most recent posting in which he determined the species of an exuvia I collected last year and be sure to explore the rest of the fantastic photos and info in his blog.

Michael Powell collected several odonate exuviae during a photowalk along the Potomac River in Fairfax County, Virginia USA, including two damselflies and two dragonflies. The exact date is uncertain, although Mike thinks the exuviae were collected sometime between 19-23 July 2017.

Both dragonfly exuviae are from the Family Gomphidae (Clubtails), as indicated by a flat labium that doesn’t cover the face as well as club-like antennae. Notice that abdominal segment nine (S9) is elongated, strongly suggesting this individual is a member of the genus Stylurus.

The dichotomous key for Stylurus larvae that appears on pp. 310-312 in Dragonflies of North America, Third Edition by Needham et al. was used to identify the species of the exuvia. The ninth couplet [9, 9′] is as follows.

9(7’). Length of abdominal segment 9 at least equal to its basal width; lateral spines of abdominal segment 9 at least…

Be sure to check out Walter Sanford’s narrative and photos of our adventures together this past Monday trying to photograph snakes. Our photographic and writing styles are different and our posts are intended to complement each other by providing alternative points of view.

Michael Powell and I met for a long photowalk at Huntley Meadows Park on 11 April 2016. We spotted (and photographed) a Northern Black Racer (Coluber constrictor constrictor) during the morning and an Eastern Gartersnake (Thamnophis sirtalis sirtalis) in the early afternoon.

Mike’s viewpoint

The following photo shows Michael Powell shooting the snake, up close and personal, using a field-tested technique I refer to as “Sandbagging the Grinder.” Sometimes Mike uses his camera bag for support and stability in order to shoot tack-sharp photos with a Tamron 180mm macro lens. “The Grinder” is my nickname for Mike’s macro lens because you can hear the internal gears grinding when it’s autofocusing — it’s loud, but hey, it works well in the hands of a skilled photographer!

Fellow dragonfly enthusiast Walter Sanford managed to spot a dragonfly in January in Northern Virginia. Wow!

Be sure to check out his blog for more facts and photos about dragonflies, damselflies, and other little creatures.

A single Autumn Meadowhawk dragonfly (Sympetrum vicinum), jokingly referred to as a “Winter Meadowhawk dragonfly” in a recent post, was observed on 03 January 2016 near the terminus of the Hike-Bike Trail at Huntley Meadows Park. This sighting sets a new late-date for this species for both Huntley Meadows Park (formerly 27 December) and the Commonwealth of Virginia (formerly 01 January).

The following graphic image shows the current air temperature in the central wetland area around the time when I spotted the record-setting dragonfly. 51°F is nearly 20 degrees less than 70°F, widely believed to be the minimum body temperature necessary for dragonfly flight!

I am not particularly fond of mosquitoes and flies landing on me, but I love it when a colorful dragonfly chooses to do so. Autumn Meadowhawks are especially friendly in this regard and my friend Walter Sanford captured some fun images of these little red beauties that had landed on different parts of his body (and even included a few photos I took of him with his little friends). Check out his posting!

The Autumn Meadowhawk dragonflies (Sympetrum vicinum) were especially “friendly” during a recent visit to Huntley Meadows Park, landing on me frequently as Michael Powell and I were searching for Great Spreadwing damselflies (Archilestes grandis).

My Photos

The following individual is a male, perching on the leg of my Columbia convertible pants. Regular readers of my photoblog know I’m especially fond of head-tilts in which the dragonfly seems to display some of its personality. Like this guy, who I imagine is thinking “What are you looking at? That’s right pal, I’m perching on your pants!”

Check out today’s posting by my good friend and fellow photographer Walter Sanford for a compelling narrative and wonderful photos of our newest adventures searching for the Great Spreadwing damselfly.

It was my honor to spend Veterans Day with my good friend and photowalking buddy Major Michael Powell, U.S. Army, Retired. We were men on a mission: Searching for Great Spreadwing damselflies (Archilestes grandis), in the hope of extending the “official” late-date for this species in Virginia. Mission accomplished, but it wasn’t easy — the operation was unsuccessful until we called in an “air strike!”

Since 06 October 2015, Mike and I have been frequently monitoring the Great Spreadwing damselflies that inhabit a small permanent pond and surrounding fields at a remote location in Huntley Meadows Park.

On 11 November, Mike and I spent several hours intensively searching for our quarry; no luck. A little after 1:00 p.m., we were standing near the pond watching a lone Shadow Darner dragonfly (Aeshna umbrosa) aggressively hawking smaller odonates perching around the perimeter of the pond: the darner dipped into…

In vain I have searched this month for Common Sanddragon dragonflies at the places where I spotted them earlier this season. My good friend and fellow photographer and blogger, Walter Sanford, captured some beautiful shots of the last ones that we spotted. Be sure to check out the other wonderful photos and fascinating information in his blog.

walter sanford's photoblog

Common Sanddragon (Progomphus obscurus) is a member of the Clubtail Family of dragonflies that is spotted during June and July in mid-Atlantic United States like Virginia. Common Sanddragons are habitat specialists that prefer sandy woodland streams, so don’t look for them in wetland areas like the hemi-marsh at Huntley Meadows Park.

This post features two male Common Sanddragon dragonflies, as indicated by their terminal appendages. As fate would have it, they are the last Sanddragons spotted during Summer 2015.

The water level was near the top of the stream banks after near record-setting rainfall for the month of June. (Notice the discoloration of the vegetation from siltation during a recent flood.)

The conditions for hunting Sanddragons were less than ideal. Male Common Sanddragons prefer perching on a sandy beach, facing the water; there weren’t any beaches, so Sanddragons were…
