Gray Petaltail dragonfly (male, No. 3)

July 6, 2020

Several Gray Petaltail dragonflies (Tachopteryx thoreyi) were spotted during a recent photowalk with Michael Powell at a location in Fairfax County, Virginia USA. This one is No. 3 of 4.

After shooting a “record shot,” I like to “work the shot,” that is shoot the subject from all viewpoints. In this case the range of possible shots was somewhat limited so after I felt like I’d taken all the shots I could, I challenged Mike to see how close he could get to the dragonfly.

As you can see in the photo featured in The Backstory, it turns out Mike was able to get astoundingly close to this very cooperative Gray Petaltail!

The Backstory

The Panasonic Lumix DMC-FZ300 is one of two superzoom bridge cameras that I use as my “go to” rigs for photowalking. The minimum focusing distance in AF Macro mode is 1 m (3.3 feet) at maximum telephoto (600 mm, 35mm equivalent). My usual practice is to set the camera lens for maximum telephoto and move as close as possible to the minimum focusing distance, resulting in maximum magnification of the subject. That’s how I shot the three photos shown above.

The following photo is shown for scale. The Gray Petaltail is perched on a fallen tree limb approximately six inches (6″) in front of Mike Powell’s 180mm macro lens. Shooting macro is one way to increase magnification; shooting at maximum telephoto is another. I prefer the flexibility afforded by a zoom lens versus a prime lens like Mike is using.

Gray Petaltail dragonfly (male, No. 2)

June 29, 2020

Another Gray Petaltail dragonfly (Tachopteryx thoreyi) was spotted during a recent photowalk with Michael Powell at a location in Fairfax County, Virginia USA. This individual is a male, as indicated by his “indented” hind wings, and terminal appendages.

The first photo is the “record shot” for this individual, that is, “get a shot, any shot.” It’s literally the first shot I took as soon as I spotted the Gray.

13 JUN 2020 | Fairfax County, VA | Gray Petaltail (male)

I moved slowly to a slightly closer position; almost had a squared-up dorsal view of the subject before he flew away.

Gray Petaltail dragonfly (male)

June 19, 2020

A Gray Petaltail dragonfly (Tachopteryx thoreyi) was spotted during a recent photowalk with Michael Powell at a location in Fairfax County, Virginia USA. This individual is a male, as indicated by his “indented” hind wings, and terminal appendages.

The Gray Petaltail is shown perched on the sunny side of a tree where the dragonfly landed after he flew past me. This is my first photo of my first Gray for 2020.

13 JUN 2020 | Fairfax County, VA | Gray Petaltail (male)

The Gray moved to another place on the same tree. The “hairy” vine where he is perched is poison ivy. Yikes, please don’t land on me Mr. Petaltail!

13 JUN 2020 | Fairfax County, VA | Gray Petaltail (male)

The dragonfly flew to another tree nearby the first one. The next photo is my favorite in the set.

13 JUN 2020 | Fairfax County, VA | Gray Petaltail (male)

The last photo shows a side view of the Gray, featuring a partial view of his face.

Arrowhead Spiketail dragonfly (male)

June 17, 2020

An Arrowhead Spiketail dragonfly (Cordulegaster obliqua) was spotted during a recent photowalk with Michael Powell at a location in Fairfax County, Virginia USA.

08 JUN 2020 | Fairfax County, VA | Arrowhead Spiketail (male)

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

The Backstory

At the end of a long day in the field, Mike Powell and I were walking back to the car slowly when we spotted a group of 10-or-so large dragonflies hawking insects over a HUGE field, near a small drainage pipe. We stopped to watch the hawkers hoping one would land; I sat on my Coleman camp stool to rest in the shade and enjoy the aerial acrobatics show.

One of the large dragonflies zoomed past Mike (he says he never saw it) and landed on a tall grass stem near the drainage pipe. It was the male Arrowhead Spiketail shown above!

Turns out the place is nothing like the habitat described as ideal (see below). I’ll say this: Three out of four times I’ve seen Arrowhead Spiketails, a fly-by was how I found them. So maybe just sit in a good spot and wait for the game to come to you. Maybe.

Habitat

Disclaimer: I have observed and photographed four (4) Arrowhead Spiketail dragonflies. I feel somewhat uncomfortable providing habitat guidance based upon a sample size of four. That being said, here goes.

Almost every Arrowhead siting had three common ingredients: a seep (or soggy place) in the forest, with skunk cabbage (Symplocarpus foetidus) and interrupted fern (Osmunda claytoniana); a small stream in the forest fed by the seep/soggy place; and a sunny clearing.

I found my first Arrowhead Spiketail at a small stream in Huntley Meadows Park. I walked the stream to its source, not that the source is well defined. Instead it’s a BIG soggy area. I wouldn’t call it a seep and I have never seen skunk cabbage anywhere in the park. There are two virtually identical streams elsewhere in the park where Arrowhead has been photographed. The male Arrowhead flew a LONG patrol along the stream, flying approximately six inches (6″) above the water level. At the end points of his patrol, he would hang up to rest in a sunny spot. It took a long time for me to find the hang up places!

Michael Powell spotted the second Arrowhead Spiketail I’ve seen, perched in a small, sunny clearing in the forest along a small stream. A seep with skunk cabbage and interrupted fern was located nearby. For what it’s worth, we saw/photographed several Gray Petaltail dragonflies (Tachopteryx thoreyi) in the same field.

MUCH FARTHER downstream, the same creek is a little larger in size. At one point, a small iron-stained creek flows into the main creek. Mike and I were standing at the mouth of the tiny creek when I saw an Arrowhead fly like a bat out of hell straight down the stream and turn left; it perched in a large, sunny field. I was able to find it, and we took photos. A week-or-so later, Mike traced the smaller creek to its source. Wouldn’t you know it? The headwaters are a seep with lots of skunk cabbage!

My most recent Arrowhead Spiketail sighting — the individual featured in this blog post — is the one that doesn’t fit the pattern. The dragonfly was spotted in a HUGE field of grasses, etc. There are small creeks and seeps nearby, but not within sight of the location where the Arrowhead perched.

Skunk cabbage flowers

February 5, 2020

The following photo gallery shows skunk cabbage (Symplocarpus foetidus) flowers in a forest seep located at Occoquan Regional Park (ORP), Fairfax County, Virginia USA.

This is ideal habitat for Gray Petaltail dragonfly (Tachopteryx thoreyi) larvae, and in fact, numerous adult “Grays” have been observed along a sunny trail near this location. Seeps are home for some species of larvae from Family Cordulegastridae (Spiketails) as well.

The following quote is perhaps the best description of a forest seep that I’ve read.

[Some] small tributaries … have their sources in numerous woodland seeps. While a few of these perennial springs bubble up out of the ground, most arise in moist hillside patches with lots of decaying leaf litter and luxuriant stands of skunk cabbage. Source Credit: White, Harold B., III. Natural History of Delmarva Dragonflies and Damselflies (Cultural Studies of Delaware and the Eastern Shore) (Kindle Locations 1213-1215).

Gray Petaltail dragonfly (female)

August 16, 2019

A Gray Petaltail dragonfly (Tachopteryx thoreyi) was spotted during a photowalk with Michael Powell around a small seep-fed pond in the forest at an undisclosed location in Prince William County, Virginia USA.

This individual is a female, as indicated by her terminal appendages. She is perched on a small tree in a sunny clearing.

A seep is a seep is a seep.

Gray Petaltail is known to occur at a small, seep-fed pond located in the forest. Part of the seep is shown below. The female dragonfly featured in this blog post was perched on a small tree just to the left edge of the photo.

Forest seeps vary in size and associated vegetation, but wherever you find one it provides good habitat for petaltails and some species of spiketails.

“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.

Photo used with permission from Mike Powell.

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.

More “Grays” on me

August 12, 2019

Well, really just one “Gray.” Gray Petaltail dragonfly (Tachopteryx thoreyi), that is. Perched on my … er, hip. This individual is a female, as indicated by her rounded hind wings and terminal appendages.

Guest photographer Michael Powell shot both images during a photowalk with me on 21 May 2019 at an undisclosed location in Prince William County, Virginia USA.

The following photo set provides a brief example of what we call “working the shot.” The first photo is what some other ode hunters call the “record shot,” meaning get a shot, any shot of the subject in case it flies away and is never seen again.

Photo used with permission from Mike Powell.

Slowly Mike moved closer to get the shot he wanted, shown below.

The Backstory

21 May 2019 was a great day for spotting Gray Petaltail dragonflies during a long, productive photowalk with Michael Powell at two locations: along a small stream in the forest; and around a small seep-fed pond. At least a dozen (12+) T. thoreyi were observed during the day, including two “Grays” that landed on Mike.

As we were walking toward Mike’s car at the end of the day, I was feeling disappointed that we hadn’t taken any photos of T. thoreyi perched on me. That’s when I noticed a Gray Petaltail perched on a fence rail. Before I was able to take a picture of the dragonfly, she flew from the fence rail to a new perch on my backside. Fortunately Mike was close behind me and was able to shoot the good photos featured in this blog post. Needless to say, I suffered as the butt of many jokes related to my indelicate circumstance!

Another female Gray Petaltail

July 31, 2019

This blog post features two of my favorite photos of another Gray Petaltail dragonfly (Tachopteryx thoreyi) spotted during a photowalk with Michael Powell along a small stream in the forest at an undisclosed location in Prince William County, Virginia USA.

21 MAY 2019 | PNC. William County, VA | Gray Petaltail (female)

This individual is a female, as indicated by her rounded hind wings, and terminal appendages. She is perched on a large tree in a sunny clearing.

21 MAY 2019 | PNC. William County, VA | Gray Petaltail (female)

In natural sunlight, the Gray Petaltail was nearly impossible to see against the tree bark. An external flash unit added enough “fill” light so that the dragonfly “pops” with detail!
