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.

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!

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).

“Grays” on me

July 15, 2019

“Grays” on me? No, don’t eat me! (See what I did there?)

This post features images from guest photographer Michael Powell, taken during a photowalk with me at Occoquan Regional Park (ORP), Fairfax County, Virginia USA.

The photos show two different male Gray Petaltail dragonflies (Tachopteryx thoreyi) perched on me.

Photo used with permission from Mike Powell.

The last photo shows a male Gray Petaltail perched on my bucket hat. Look closely at the full-size version of the photo. Notice the dragonfly appears to be grazing upon a smaller insect. (See? I did it again!)

Photo used with permission from Mike Powell.

I call the preceding photo “Wilson Wilson” because it reminds me of a discussion between Tim “The Tool Man” Taylor and his next-door neighbor Wilson Wilson about a flying saucer that Wilson saw. See Home Improvement: Believe It or Not Clip (1:31).

Gray Petaltail dragonfly (male)

July 3, 2019

The following Gray Petaltail dragonfly (Tachopteryx thoreyi) — spotted in a sunny clearing along a small stream in the forest at an undisclosed location in Prince William County, Virginia USA — is a male, as indicated by his “indented” hind wings, and terminal appendages.

Actionable Intel

I looked for Gray Petaltail for years without finding one. (Looking for love in all the wrong places?) For habitat-specific odonates such as T. thoreyi, it’s all about location, location, location. I was familiar with the standard guidance in all the field guidebooks regarding ideal habitat for Gray Petaltail, but it wasn’t until I actually saw the right habitat in the wild — and recognized it for what it is — that I began to find Grays in relatively large numbers. Book learning is good (as Jethro would say), but there’s no substitute for real-world experience.

For example, the following photograph shows a forest seep located at Occoquan Regional Park (ORP), Fairfax County, Virginia USA. The plant with broad green leaves is skunk cabbage (Symplocarpus foetidus). This is ideal habitat for T. thoreyi, and in fact, one or more “Grays” were observed along a sunny trail near this location, including a male that landed on my friend Mike Powell.

01 JUN 2019 | ORP | forest seep, with skunk cabbage

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.

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!

“Grays” come in peace.

June 10, 2019

A Gray Petaltail dragonfly (Tachopteryx thoreyi) was spotted during a photowalk with Mike Powell at Occoquan Regional Park, Fairfax County, Virginia USA.

This individual is a male, as indicated by its “indented” hind wings and terminal appendages. The male is perched on the left sleeve of Mike’s gray “Army” logo t-shirt. I nicknamed this Gray “The Gripper” because Mike said he could feel the dragonfly tightening its grip on a small fold in the t-shirt.

“Grays”

If you look into the eyes of a Gray Petaltail dragonfly at close range, then you might agree with me that they look like the space aliens known as “Grays.” Hey, I’m just saying — Mike might have experienced a close encounter of the Gray kind!
