Dromogomphus spinosus exuvia

June 28, 2019

A dragonfly exuvia was collected by Joe Johnston on 22 May 2019 at Aquia Creek, Stafford County, Virginia USA. This specimen is the cast skin from a Black-shouldered Spinyleg (Dromogomphus spinosus) larva. D. spinosus is a member of Family Gomphidae (Clubtails).

At first I thought the exuvia might be a species from the genus Stylurus, based upon the mid-dorsal spine on abdominal segment nine (S9). After careful examination of two excellent photo-illustrated PowerPoint presentations by Kevin Hemeon at NymphFest 2016 (see Related Resources, below), I noticed none of the species in the genus Stylurus have dorsal hooks. That’s when I realized the specimen must be D. spinosus. Eureka!

The Backstory

Joe Johnston is an avid boater and sport fisherman who kindly agreed to be my “Eyes on the Aquia,” always on the lookout for odonate exuvia to share with me. On 22 May 2019 Joe caught a largemouth bass that swam around one of the wooden pilings of a boat dock that extends far into Aquia Creek. The fishing line was snagged on the piling so Joe moved his boat into position to free the fish. That’s when he noticed the exuvia clinging to a piling on the underside of the dock. Good catches, Joe!

Tech Tips

The following equipment was used to shoot the quick-and-dirty handheld macro photograph featured in this post: Fujifilm X-T1 digital camera; and Fujinon XF80mm macro lens plus lens hood. The camera was set for both manual exposure and manual focus. That’s right, a switch on the camera body is used to set the type of focus. It’s a Fujifilm thing. Actually, back-button focus was used to autofocus the image and adjusted manually as necessary. That’s also a Fujifilm thing. Camera settings: focal length 80mm (120mm, 35mm equivalent); ISO 200; f/9; 1/180s.

Godox XProF radio flash trigger, mounted on the hotshoe of my X-T1, was used to control an off-camera Godox TT685 Thinklite TTL Flash (TT685F) set for radio slave mode. The flash was fitted with a Lastolite Ezybox Speed-Lite 2 flash modifier.

Adobe Photoshop CC 2017 was used to spot-heal and sharpen the image, plus add annotations.

Sometime in the future (probably the odonate “off-season”) I will create higher quality composite images of this exuvia, shown from all viewpoints including the ventral view. As it turns out, the dorsal view is sufficient to identify this species.

Dragonflies rock!

May 15, 2019

I received a surprise parcel in the U.S. Mail from my dear friend Susan Kinsley. There was a cover note inside the box…

The church where I work has a ministry where they paint rocks and then place them in the community for people to find to brighten their day. When I saw this one in the basket, I decided that you needed to have it. The woman in charge of the ministry gave me permission to take it and send it, rather than trying to hide it at Huntley Meadows or somewhere you might, or might not, find it. Enjoy! Susan

There’s a friend who knows me well. Thanks for thinking of me, Susan. God bless you!

Aging gracefully

March 1, 2019

The following gallery features several photos of a Valentines Day gift of appreciation from The Beacon of Groveton. A little more than two weeks after the red rose was delivered, the flower appears to be aging gracefully.

I experimented with a different lighting setup than the last photo shoot of this flower. An articulating Loc-line arm was used to hold and pose the cut flower. The background is a 12″ x 12″ piece of white plastic, mounted vertically and backlighted by a radio-controlled external flash unit. Notice the vignetting on the left side of the photo, caused by the flower being offset from the center of the sweet spot of the backlight.

The simplest solution to the vignetting problem is to crop the image. Ah, much better, and much closer to achieving my vision for the finished product — the red rose posed against a clean white background!

The next photo is the only photo in the set that turned out exactly as I wanted. Well, the flash in Group B (off camera, to the front-left of the subject) is a little too bright, but that’s just the perfectionist in me talking.

28 FEB 2019 | BoG Photo Studio | Valentines Day rose

The first two photos were taken at f/8. I moved the camera closer to the subject for the last photo and switched to f/11 for more depth of field. The shadow of the flower stem on the white background wasn’t part of my plan — I’m not sure whether it adds to the photo or detracts. What do you think?

Sometimes you just need to stop…

February 20, 2019

…and smell, er, see the roses. Seriously, man doesn’t live by odonates alone!

The following gallery features several photos of a Valentines Day gift of appreciation from The Beacon of Groveton. Nearly a week after the red rose was delivered, it’s beginning to show a little “character.”

Test shots: “Generic Baskettail?”

February 15, 2019

larva/nymph in the Family Corduliidae (Emeralds) was collected by Bob Perkins on 02 December 2017 from a pond in Orange Park, Florida (USA). The larva died before it metamorphosed into an adult.

Test shots of this beautifully preserved specimen were taken using a small-ish aperture of f/11 for greater depth of field. The following photos are “one-offs,” that is, not composite images.

Dorsal

A single focus point — located on the thorax (specifcally, the “shoulder pad” along the right side of the body) — was used to shoot this photo. The specimen has enough “relief” that focus on the wing pads and dorsal hooks is slightly soft. This view of the larva is a good candidate for focus-stacking.

The terminal appendages (cerci, epiproct, paraprocts) are shown clearly in the following photo.

Bob’s best guess of the identity of the specimen is Epitheca sp., either Common Baskettail (Epitheca cynosura) or Prince Baskettail (Epitheca princeps).

Whenever I see an odonate larvae/exuviae with long legs, my first thought is Family Macromiidae (Cruisers). Then I check for a horn on top of the head, a key field marker for Cruisers. Look closely at the dorsal view of the larva and I think you’ll agree with me there appears to be a horn on the head. I would like to take close-up photos of the head and key out the specimen in order to determine its identity. In the meantime, my best guess is Stream Cruiser (Didmops transversa) as indicated by the lateral spines on abdominal segment nine (S9) and the absence of a dorsal hook on S10.

Ventral

The ventral side of the specimen has almost no “relief,” so a “one-off” focused on the thorax looks fairly good from head-to-tail.

Composite images: “Generic Gomphid”

February 13, 2019

“It’s like Deja vu all over again.” (Source Credit: Yogi Berra.) But seriously folks, if you were thinking “Hey these pictures look familiar!” then you’re right. My last blog post features “one-offs” of the same subject, that is, photos with a single focus point on the mid-body of the specimen.

This post features focus-stacked composite images that show dorsal- and ventral views of a preserved larva in the Family Gomphidae (Clubtails) that was collected by Bob Perkins. I think both composite images look better than the “one-offs” in my last blog post; the difference is especially noticeable by looking at the head and tail in the vernal view.

Dorsal

Five (5) photos were used to create the first focus stack. A single focus point was positioned over select anatomical features; photos were taken at each point of interest.

Six (6) photos were used to create the second focus stack.

Test shots: “Generic Gomphid”

February 11, 2019

A larva/nymph in the Family Gomphidae (Clubtails) was collected by Bob Perkins from the New River in southwestern Virginia. The larva died before it metamorphosed into an adult.

Test shots of this beautifully preserved specimen were taken using a small-ish aperture of f/11 for greater depth of field. The following photos are “one-offs,” that is, not composite images.

Dorsal

80mm (120mm, 35mm equivalent) | ISO 200 | f/11 | 1/180 s | 0 ev

Bob’s best guess of the identity of the specimen is Phanogompus sp. I see several similarities between this larva and a Phanogomphus lividus exuvia (Ashy Clubtail) in my collection, so Bob’s tentative identification might be correct. More later after the specimen is keyed out.

Ventral

80mm (120mm, 35mm equivalent) | ISO 200 | f/11 | 1/180 s | 0 ev

This individual might be female, as indicated by the rudimentary ovipositor that can be seen on the ventral side of the specimen along the boundary between abdominal segments eight and nine (S8-9).

By the way, in case you looked at the preceding photo and wondered “What’s up with the crazy crop?” I used Photoshop to conceal some of the clutter in my kitchen. I set up my macro photo rig in the kitchen because it’s the largest uncarpeted area in my tiny apartment. Padded carpet is a poor surface for macro photography — the field of view from a tripod-mounted camera-lens-flash trigger combo shifts noticeably (and unacceptably) as one moves around the rig.

The other side of “What is it?”

January 21, 2019

The following photograph shows the wooden side of a dragonfly rubber stamp.

The Backstory

On 26 December 2017, I published a blog post entitled “What is it?” I was testing my new Fujinon XF80mm macro lens used in combination with a Fujifilm MCEX-11 extension tube and needed a small subject to photograph. I was also testing my new Canon MT-26EX-RT Macro Twin Lite used in manual mode with my Fujifilm X-T1 digital camera.

In this case, I was testing — actually retesting — my new Fujifilm MCEX-16 extension tube. The last time I tested the 16mm extension tube, I used it in combination with an 11mm extension tube. Bottom line, I wasn’t happy with the results. So I decided to test the 16mm tube by itself, decrease the f-stop to a value closer to the sweet spot of the lens, and increase the exposure. Much better!

More power!

January 18, 2019

Like Tim “The Tool Man” Taylor, I like/need more power. (Grunt, grunt.) Regular readers of my photo blog know that I have purchased several new external flash units and related accessories, all of which use batteries as their power source.

Panasonic eneloop pro rechargeable batteries and Ansmann Battery Boxes are my current favorite brands.

Panasonic eneloop pro rechargeable batteries | Ansmann Battery Box

Look closely at the full-size version of the preceding photo. Notice that the month and year I bought the batteries is written on the side of each battery using a Sanford’s Sharpie permanent marker. I do this for two reasons. First, it’s easier to group/use batteries of the same vintage. Second, it’s easier know when it’s time to replace a set of batteries that doesn’t hold a charge as long as it used to.

The little things matter in photography. Little things like batteries, especially when you’re photowalking in the field. I always carry at least two boxes of four batteries per box.

More test shots: Ladona deplanata exuvia

January 16, 2019

As promised, this blog post features more test shots of the exuvia from a Blue Corporal dragonfly (Ladona deplanata) larva/nymph collected and reared by Bob Perkins.

All of the images in this photo set (including the dorsal view featured in my last blog post) are underexposed, except for the following photo: this photo looked overexposed on my camera LCD; the rest of the photos looked fine.

In reality, the photos were underexposed because I didn’t compensate for the effect of the extension tubes on exposure — a problem that was probably caused/exacerbated by switching the ISO from my usual setting of “A” (Auto) to 200. This photo turned out to have the best exposure because the flash power was several stops higher than the rest of the photos in the set. Remember the exposure triangle. (See Tech Tips/Related Resources, below.)

Oh, so close to a good shot! The left front leg blocks part of the face-head, and that doesn’t work for me. This specimen is a good candidate for rehydrating the exuvia and reposing its legs.

What you should remember, as a rule of thumb, is that by the time you get close to magnifications of 1:1, the effective f-stop of the lens will have changed by about 2 stops. That means you, or your camera, are needing to compensate for this with a higher ISO, or a shutter speed that’s 4-times longer than you’d need without those tubes.
