“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.

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.

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!

Blue Corporal dragonfly (mature male)

July 19, 2019

I like to take some test shots/warm-up shots at the beginning of every photowalk, in order to check exposure, etc. and practice muscle memory. The idea is simple: Prepare to shoot before I see something rare to uncommon, as happened on 21 May 2019.

21 MAY 2019 | PNC. William County, VA | Blue Corporal (mature male)

A Blue Corporal dragonfly (Ladona deplanata) was spotted near a small pond at an undisclosed location in Prince William County, Virginia USA. This individual is a mature male, as indicated by its coloration and terminal appendages.

Great day for Gray Petaltails!

July 17, 2019

At least a dozen (12+) Gray Petaltail dragonflies (Tachopteryx thoreyi) were 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 (male)

A nearly equal number of females and males were observed. This individual is a male, as indicated by his “indented” hind wings, and terminal appendages. He is perched on a fallen tree in a sunny clearing.

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 T. thoreyi is 12 April to 09 August. The species is classified as uncommon. Its habitat is “seepage areas.”

Bear in mind, Dr. Roble’s records are for the entire state, therefore the adult flight period for T. thoreyi seems to be longer than it is in reality. The adult flight period for a single site is probably shorter — more likely around one month-or-so. For example, according to records for Northern Virginia maintained by Kevin Munroe, former manager of Huntley Meadows Park, the adult flight period for Gray Petaltail is 24 June to 25 July (peaks in late-June/early-July).

Gray Petaltail dragonfly (male)

June 19, 2019

Gray Petaltail dragonflies (Tachopteryx thoreyi) have a well-known preference for perching on gray or tan colored surfaces, including gray or tan colored clothing.

Most of the photos of Gray Petaltail featured in my blog show them perched on gray/grayish surfaces. In contrast, the following Gray Petaltail is perched on a mostly tan colored tree.

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

This individual — spotted in a sunny clearing along a small forest stream at an undisclosed location in Prince William County, Virginia USA — is a male, as indicated by his “indented” hind wings, and terminal appendages.

The preceding photo is uncropped, that is, full resolution for the Panasonic Lumix DMC-FZ300 superzoom bridge camera (4,000 x 3,000 pixels). Needless to say, I was fairly close to this cooperative subject!

Painted Skimmer dragonfly (female)

June 3, 2019

A Painted Skimmer dragonfly (Libellula semifasciata) was observed during a photowalk with my good friend Mike Powell along a small forest stream at an undisclosed location in Prince William County, Virginia USA.

21 MAY 2019 | PNC. William County, VA | Painted Skimmer (female)

This individual is a female, as indicated by her terminal appendages.

Habitat

Look for Painted Skimmer near some sort of water body in the forest, such as a vernal pool or small streams and ponds.

Aurora Damsel (male, mating pair)

May 31, 2019

An Aurora Damsel (Chromagrion conditum) was spotted along the shoreline of a small pond located in Prince William County, Virginia USA. Aurora Damsel is a new species for my life list odonates.

This individual is a male, as indicated by his coloration and terminal appendages. Speaking of coloration, notice the underside of the male’s thorax is yellow — a key field mark for Aurora.

21 MAY 2019 | PNC. William County, VA | Aurora Damsel (male)

A mating pair of Aurora Damsel was spotted at the same location. This pair is “in tandem“: the male is on the upper-right; the female on the lower-left.

After copulation, Aurora Damsel engages in a form of guarding behavior known as “contact guarding,” in which the male and female fly “in tandem” to egg-laying sites. Contact guarding is used by most species of damselflies and some species of dragonflies to prevent aggressive males from hijacking the female.

21 MAY 2019 | PNC. William County, VA | Aurora Damsel (mating pair)

Female C. conditum is polymorphic, including two morphs: blue coloration similar to male; or with an entirely yellow thorax, as shown above.

It’s helpful to take photos of mating pairs of damselflies, especially “in tandem,” since males and females of the same species can look quite different. The preceding photo is slightly overexposed. As a result, the yellow coloration on both the male and female looks a little washed out.

Credits

Sincere thanks to Gary Myers for the tip that enabled Mike Powell and me to find this uncommon damselfly. See Aurora Damsels in action for Mike’s take on our first time seeing this species.
