“Big Boy”

July 19, 2017

Several Eastern Ringtail dragonflies (Erpetogomphus designatus) were spotted along the Potomac River at Riverbend Park, Fairfax County, Virginia USA. These individuals are male, as indicated by their terminal appendages and “indented” hind wings.

All of the photos in this set were taken using my Fujifilm X-T1 digital camera, Fujinon 100-400mm telephoto zoom lens, and Fujifilm EF-X500 shoe mount flash.

I nicknamed the Fujinon 100-400mm lens “Big Boy” because it’s so big and heavy. I use a Sunpak 6700M monopod and Vanguard SBH 100 ball head to support the lens.

Zoom in on the full-size version of the preceding photo. Notice the terminal appendages are spread apart, revealing a clear look at both the cerci and hook-shaped epiproct.

Related Resource: You complete me – a blog post published on 19 February 2016 in which I shared my first impressions of the Fujinon 100-400mm telephoto zoom lens.

Lancet Clubtail dragonfly (male)

June 25, 2017

A Lancet Clubtail dragonfly (Phanogomphus exilis) was spotted during a photowalk at “Straight Fork Beaver Ponds,” Highland County, Virginia USA. This individual is a male, as indicated by his terminal appendages and “indented” hind wings.

09 JUN 2017 | Highland County, VA | Lancet Clubtail (male)

This male Lancet Clubtail was spotted at the same location as a male Harpoon Clubtail dragonfly (Phanogomphus descriptus) featured in a previous post. Lancet Clubtail is a relatively widespread species of odonate, in contrast with Harpoon Clubtail.

Bonus Bug

Look closely at the preceding photo. Did you notice the exuvia from another type of aquatic insect, possibly either mayfly or stonefly? I didn’t see the exuvia when I shot the photo, and missed them again when I post-processed the image. Sometimes I get so focused on the subject that I don’t see the bigger picture.

Tech Tips

The photos were taken using a Fujifilm X-T1 digital camera, Fujinon 55-200mm zoom lens, and Fujifilm EF-X500 shoe mount flash.

Another record shot

June 23, 2017

A Black-shouldered Spinyleg dragonfly (Dromogomphus spinosus) was spotted by Mike Boatwright during a photowalk at Columbia Boat Landing, Cumberland County, Virginia USA. This individual is a female, as indicated by her terminal appendages and rounded hind wings.

This photo is a “record shot” of another species of dragonfly spotted during a road trip with Mike to two locations along the James River in central Virginia. Not my best work, but hey, the photo provides documentation of the first Black-shoulder Spinyleg I’ve seen this year. With any luck, it won’t be the last.

Tech Tips

The photo was taken using a Fujifilm X-T1 digital camera, Fujinon 55-200mm zoom lens, and Fujifilm EF-X500 shoe mount flash.

“Record shot”

June 21, 2017

As a wildlife photographer with a focus on insect photography, one of my mantras is: “Get a shot, any shot; refine the shot.” In other words, don’t miss the opportunity to document a spotting by trying to get a great shot first.

11 JUN 2017 | Fluvanna County, VA | Dragonhunter (male)

The preceding photograph — heavily-cropped in order to compensate for the distance to the subject — is a “record shot” (at best) of a male Dragonhunter dragonfly (Hagenius brevistylus) that was spotted at the Hardware River Wildlife Management Area, Fluvanna County, Virginia USA.

The dragonfly was photographed from the banks of the Hardware River, approximately 20 feet above the water. Distance seems to be compressed in the photo, an effect of the mid-range telephoto lens used to take the shot. The Dragonhunter was perching ~10 feet above the water. I settled for a “record shot” since there was no way to get closer to the subject.

Tech Tips

The photo was taken using a Fujifilm X-T1 digital camera, Fujinon 55-200mm zoom lens, and Fujifilm EF-X500 shoe mount flash. Adobe Photoshop was used to remove a small distracting element from the left edge of the photo.

Editor’s Note

Thanks to fellow Virginians Karen Kearney and Mike Boatwright for adding the phrase “record shot” to my vocabulary.

Allegheny River Cruiser dragonfly (male)

June 19, 2017

An Allegheny River Cruiser dragonfly (Macromia alleghaniensis) was netted by Mike Blust at Hardware River Wildlife Management Area, Fluvanna County, Virginia USA.

The complete yellow ring around abdominal segment seven (S7) is a distinctive field marker for this species. This individual is a male, as indicated by his hamules and terminal appendages.

Allegheny River Cruiser is a good candidate for netting, that is, if you want to get a close look at one.

Males fly rapidly up and down streams, mostly but not always near shore, usually quite low… . Cruise up and down roads through woodland, in sun and shade, or fly up higher into forest canopy. Source Credit: Paulson, Dennis (2011-12-19).

Allegheny River Cruiser is a new species of dragonfly for my life list.

Tech Tips

The photo was taken using a Fujifilm X-T1 digital camera, Fujinon 55-200mm zoom lens, and Fujifilm EF-X500 shoe mount flash.

My camera had a mysterious meltdown when I was trying to photograph the dragonfly in Mike Blust’s hand. Sincere thanks to Mike for his extraordinary patience while I was troubleshooting the problem under extreme pressure.

Editor’s Note

Sincere thanks to Mike Boatwright for taking me to a couple of odonate-hunting localities along the James River, including Hardware River WMA (see map, shown below) and Columbia Boat Landing, Cumberland County, Virginia.

The Backstory

I attended the 2017 Dragonfly Society of the Americas Annual Meeting in Staunton, Virginia, 09-11 June 2017. Yes Virginia, there is an organization called the Dragonfly Society of the Americas (DSA). Although I’ve been a member of DSA since August 2011, the 2017 annual meeting is the first one that I’ve attended.

Staunton, Virginia is the county seat of Augusta County. Highland County is located between the western boundary of Augusta County and the border between Virginia and West Virginia. Highland County is the only place in Virginia where there are official records for Harpoon Clubtail.

In the world of odonates, there are habitat generalists and habit specialists. Harpoon Clubtail is a habitat specialist, as shown clearly by the preceding distribution map of official records.

I was fortunate to be able to ride along with fellow Virginians Karen Kearney and Mike Boatwright for a road trip to Highland County. Straight Fork Beaver Ponds is a unique high-elevation habitat that is well known among expert birders and odonate hunters like Karen and Mike.

Mike scouted the location a week-or-so before the DSA meeting, so he had a good idea of the species of odonates we might see, including Harpoon Clubtail and Riffle Snaketail (Ophiogomphus carolus) dragonflies.

Sincere thanks to Karen and Mike for a fun, productive day hunting odonates with good friends!

Testing 1, 2, 3.

June 11, 2017

During a trip to Riverbend Park on 09 May 2017 to observe the annual mass emergence of Cobra Clubtail dragonflies (Gomphurus vastus), I experimented with my Fujifilm X-T1 digital camera, Fujinon XF55-200mm zoom lens, and Fujifilm EF-X500 shoe mount flash.

The first photo shows a male perching on the pavement near the boat ramp at the park. Regular readers of my photoblog know I’m fond of head-tilts in which the dragonfly seems to display some of its personality.

200mm (300mm, 35mm equivalent) | f/11 | 1/500s | ISO 800 | +1 ev

The last two photos show a female, perching on a fence rail.

200mm (300mm, 35mm equivalent) | f/11 | 1/500s | ISO 800 | 0 ev

200mm (300mm, 35mm equivalent) | f/11 | 1/500s | ISO 800 | 0 ev

Tech Tips: My Fujifilm X-T1 digital camera was set for manual aperture, manual shutter speed, and automatic ISO; the EF-X500 external flash was set for ETTL.

I like to use relatively fast shutter speeds in order to reduce camera shake, resulting in more tack-sharp photos. The default flash sync speed of the X-T1 is 1/180s. (Actually, up to 1/250s works.) My new EF-X500 external flash is high-speed sync compatible so I was able to shoot at shutter speeds faster than the sync speed of the camera, in this case 1/500s. The reciprocal rule says I should have used a shutter speed of at least 1/600s at a focal length of 300mm, but I decided to go conservative and shoot at a slightly slower speed. Most of my photos turned out to be acceptably sharp.

At f/11 and 1/500s, the camera increased the ISO to 800. That’s higher than I prefer to shoot, but hey, the photos look relatively noise-free so no problem.

In my opinion, the EF-X500 external flash was consistently underpowered in ETTL mode. During follow-up testing, I rediscovered something I learned a long time ago: If you want to control the way a photo turns out, then Manual Mode is the way to go.

Cobra Clubtail external reproductive anatomy

May 28, 2017

I liked to make paper- and plastic models when I was a child. Seems like the directions for assembling many models — not that anyone reads the directions — always started by saying something like “Insert Tab A in Slot B.”

Oddly enough, that line reminds me of how odonates copulate, in general, and Cobra Clubtail dragonflies (Gomphurus vastus) in particular.

Male

The hamules are “Tab A.”

Female

The subgenital plate is “Slot B.”

Putting it all together

Insert Tab A in Slot B. That’s the PG-rated version of how Cobra Clubtail dragonflies copulate in order to reproduce.

The Backstory

There is an annual mass emergence of Cobra Clubtails during the first week-or-two of May at Riverbend Park. It’s a spectacular event worth seeing firsthand!

The following photo shows a dead female, one of several Cobra Clubtails that were trampled by groups of elementary school children visiting the park on 09 May 2017. Her premature death saddens me because it was avoidable — the students should have been warned to watch their step because there were lots of Cobra Clubtails perching on the ground almost everywhere.

In the hope the female didn’t die in vein, I reluctantly decided to photograph the corpse in order to illustrate her external reproductive anatomy.

Editor’s Note: Sincere thanks to Dennis Paulson for help in identifying the female parts on the ventral side of abdominal segments eight and nine (S8-9).

Because it’s fun!

May 16, 2017

Why do I hunt odonates, that is, dragonflies and damselflies? I like being outdoors, visiting beautiful natural places. I like honing my skills as a wildlife photographer. Most importantly, it’s fun! I like the challenge of finding uncommon species, and the thrill of making new discoveries.

A Cobra Clubtail dragonfly (Gomphurus vastus) was spotted along the Potomac River at Riverbend Park, Fairfax County, Virginia USA. This individual is a male, as indicated by his terminal appendages and indented hind wings.

The male was perching on colorful kayaks stored in a wooden rack near the boat ramp. Notice the natural coloration of the dragonfly was affected by light reflected from the kayaks. That’s OK since this photo set is all about fun, right?

09 MAY 2017 | Riverbend Park | Cobra Clubtail (male)

Can you say “hamules?” Males of many species in the Family Gomphidae (Clubtails) have prominent secondary sex organs.

Tech Tips: I carried two digital cameras during the trip to Riverbend Park: a Panasonic DMC-FZ150 superzoom bridge camera plus Canon 580EX Speedlite, my go-to kit for photowalking; as well as my Fujifilm X-T1Fujinon XF55-200mm zoom lens, and Fujifilm EF-X500 shoe mount flash. Since Fujifilm digital cameras are well-known for capturing vivid color, the X-T1 was the camera of choice for this colorful scene.

Editor’s Note: 16 May is the one-year anniversary of my first visit to Riverbend Park to see the annual mass emergence of Cobra Clubtail dragonflies that occurs during the first two weeks in May.
