We have a history

August 21, 2020

An Eastern Pondhawk dragonfly (Erythemis simplicicollis) was spotted during a photowalk with Michael Powell near Mulligan Pond at Jackson Miles Abbott Wetland Refuge (JMAWR) in Fairfax County, Virginia USA.

This individual is a female, as indicated by her coloration and terminal appendages. Eastern Pondhawk, especially female E. simplicicollis, are voracious predators.

The Backstory

As the title of this blog post suggests, Eastern Pondhawk and I have a history — a negative history. A cohort of Southern Spreadwing damselflies (Lestes australis) was observed for a two-week period during early May 2015 at a vernal pool in the forest at Huntley Meadows Park.

The sudden disappearance of the damselfly cohort seemed to coincide with a population explosion of Eastern Pondhawk in mid-May. After years of heavy predation by Eastern Pondhawk, Southern Spreadwing disappeared completely from the vernal pool.

Blue-faced Meadowhawk (young male)

November 8, 2019

A Blue-faced Meadowhawk dragonfly (Sympetrum ambiguum) was spotted near a vernal pool in the forest at Huntley Meadows Park, Fairfax County, Virginia USA.

This individual is a young male, as indicated by the red pruinescence that partially covers his yellow-orange and black abdomen, plus his terminal appendages.

Regular readers of my photoblog know I’m fond of head-tilts in which the dragonfly seems to display some of its personality, especially when the individual is looking at me (below).

Left, right, left. I followed this guy from perch to perch for several minutes.

The Backstory

My collection of field notes includes two text files that list lots of photos of both Blue-faced Meadowhawk and Autumn Meadowhawk dragonflies (S. vicinum) that were never published in my photoblog. Most of the photos were taken during Fall 2013 when one of many vernal pools at Huntley Meadows Park was near peak diversity for odonate species that inhabited the pool. Sadly, those days are long gone!

Beetlejuice

October 31, 2018

Look closely at the following photograph and ask yourself “What’s wrong with this picture?”

12 JUN 2018 | Fairfax County, VA | Sable Clubtail (male)

Did you notice the dragonfly’s head is turned upside-down? That reminds me of the movie Beetlejuice (1988). Happy Halloween!

12 JUN 2018 | Fairfax County, VA | Sable Clubtail (male)

All three photos show the same Sable Clubtail dragonfly (Stenogomphurus rogersi), perched alongside a small stream located in Fairfax County, Virginia USA. This individual is a male, as indicated by his indented hind wings and terminal appendages. Notice his head is upside-up in the last two photos.

Related Resource: Cobra Clubtail head-tilts, featuring a female with her head positioned nearly upside-down. I guess the upside-down head thing is characteristic of some members of Family Gomphidae (Clubtails).

Lumix loves him some head-tilts!

November 6, 2017

An Autumn Meadowhawk dragonfly (Sympetrum vicinum) was spotted at Hidden Pond, Meadowood Recreation Area, Fairfax County, Virginia USA. This individual is a male, as indicated by his terminal appendages.

Regular readers of my photoblog know I’m fond of head-tilts in which the dragonfly seems to display some of its personality, especially when the individual is looking at me (below).

OK, so no head-tilt in the last photo, but I like the knot in the wooden dock on which the dragonfly is perching.

Tech Tips

The photographs in this gallery were taken using my Panasonic Lumix DMC-FZ150 superzoom digital camera set for ~24x zoom (focal length of 600mm, 35mm equivalent), and Canon 580EX Speedlite external flash (manual mode).

In order to reduce “camera shake,” the camera was set for shutter priority mode. Using the reciprocal rule, the shutter speed was set for 1/800s. The ISO was set for “100.” An inexpensive Sunpak 6700M aluminum monopod was used for added stability.

Banded Pennant dragonflies (males)

August 12, 2017

Several Banded Pennant dragonflies (Celithemis fasciata) were spotted at Mulligan Pond, Jackson Miles Abbott Wetland Refuge (JMAWR), Fairfax County, Virginia USA. All of the individuals in this gallery are male, as indicated by their terminal appendages.

Fujifilm X-T1

The first photo was taken using my Fujifilm X-T1 digital camera, Fujinon XF55-200mm zoom lens plus a Fujifilm 11mm extension tube, and Fujifilm EF-X500 shoe mount flash. The lens was set for a focal length of 200mm (~300mm, 35mm equivalent).

The camera was set for an aperture of f/11. I forgot to decrease the aperture to f/16 (one of the lessons learned from recent field testing). Although depth of field (DoF) wasn’t an issue for the lateral view of a male Swift Setwing dragonfly featured in my last post, DoF is an issue for this viewpoint of a male Banded Pennant dragonfly. Notice the head and thorax are in focus; the terminal appendages are not.

Panasonic Lumix DMC-FZ150

The photos in the last set were taken using my Panasonic Lumix DMC-FZ150 superzoom bridge camera plus Canon 580EX Speedlite, my go-to kit for photowalking.

02 AUG 2017 | JMAWR | Banded Pennant (male)

Is that a head-tilt I see below? Did you notice the male Variable Dancer damselfly (Argia fumipennis) in the background?

Editor’s Notes

What are the take-aways from looking at photo sets of the same subject taken using different camera kits, shown head-to-head?

First, the Fujifilm X-T1 is a good camera that I should use more often. My comfort level with the Fujifilm camera isn’t the same as my trusty Panasonic, but that should develop in time.

Second, the Panasonic Lumix DMC-FZ150 is capable of capturing high-quality photographs, especially when used in combination with a good external flash unit such as the Canon 580EX Speedlite.

Swift Setwing dragonflies (males)

August 10, 2017

Several Swift Setwing dragonflies (Dythemis velox) were spotted at Mulligan Pond, Jackson Miles Abbott Wetland Refuge (JMAWR), Fairfax County, Virginia USA. All of the individuals in this gallery are male, as indicated by their terminal appendages.

Panasonic Lumix DMC-FZ150

The photos in the first set were taken using my Panasonic Lumix DMC-FZ150 superzoom bridge camera plus Canon 580EX Speedlite, my go-to kit for photowalking. Many of these photos are uncropped; some of the images were cropped slightly in order to improve composition.

Male Swift Setwings prefer perching on low vegetation overlooking water. The first two photos show males perching briefly away from the shoreline.

I think the next two photos are strong candidates for my Odonart© Portfolio. What do you think?

02 AUG 2017 | JMAWR | Swift Setwing (male)

02 AUG 2017 | JMAWR | Swift Setwing (male)

The last two photos were taken within minutes of each other using two different camera kits. Is that a head-tilt I see below?

Fujifilm X-T1

02 AUG 2017 | JMAWR | Swift Setwing (male)

The last photo in this gallery was taken using my Fujifilm X-T1 digital camera, Fujinon XF55-200mm zoom lens plus a Fujifilm 11mm extension tube, and Fujifilm EF-X500 shoe mount flash. The lens was set for a focal length of 200mm (~300mm, 35mm equivalent).

The camera was set for an aperture of f/11. I forgot to decrease the aperture to f/16 (one of the lessons learned from recent field testing), although depth of field wasn’t an issue from this viewpoint of the dragonfly.

Eastern Ringtail dragonflies (males)

July 15, 2017

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

Regular readers of my photoblog know I’m fond of head-tilts in which the dragonfly seems to display some of its personality, especially when the individual is looking at me. Like the male featured in the following photo — one of my all-time favorites!

In my opinion, the unique coloration of Erpetogomphus designatus rivals Genus Ophiogomphus (Snaketails). There, I said it!

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.

Personality

March 9, 2017

In my experience, some dragonflies have a personality. Like this male Banded Pennant dragonfly (Celithemis fasciata) spotted at Hidden Pond, Meadowood Recreation Area, Fairfax County, Virginia USA.

I photographed two other male Banded Pennants; both of them were relatively skittish. Not this guy. It’s like he sensed I wasn’t a threat to his well-being and allowed me to get up close and, well, personal.

Regular readers of my photoblog know I’m fond of head-tilts — one way in which dragonflies seem to display some of their personality. Both shots show a slight head-tilt to the left.

Painted Skimmer dragonflies (males)

December 4, 2016

Several Painted Skimmer dragonflies (Libellula semifasciata) were spotted at a vernal pool in Huntley Meadows Park. All of these individuals are males, as indicated by their terminal appendages.

Sometimes you need to stop and smell the “soft rush” (Juncus effusus), the common name for the shoreline/emergent plant with a light green round stem and brownish-green flowers shown in the following photo. Soft rush is common in wetland areas.

You may be wondering, “Do dragonflies have a sense of smell?” The surprising answer can be found in an interesting article from Science magazine: Dragonflies Lack ‘Smell Center,’ but Can Still Smell.

The second and third photos in this gallery show the same male. Regular readers of my photoblog know I love a good head-tilt, shown below.

The following male must be a member of the Democratic Party, based upon his viewpoint to the left. Hah! I couldn’t resist a little good-natured jab at my friends from the opposition party who are still suffering over the outcome of the recent USA presidential election.

The last one’s for you, Michael Powell. Turns out it’s a rare photo (well, rare for me) shot in Aperture priority mode — looking along the barrel of the body, thought I’d need more depth of field.
