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.

Golden Boy

July 5, 2019

A Needham’s Skimmer dragonfly (Libellula needhami) was spotted at Occoquan Regional Park (ORP), Fairfax County, Virginia USA.

This individual is an immature male, as indicated by his coloration and terminal appendages. The yellowish-red coloration of this specimen could mislead you into thinking it’s a female. Be aware that the same species of dragonfly may appear differently depending upon gender, age, and natural variation.

At this stage in the male’s maturation, his coloration is similar to females of the same species. As a mature male, the front of his thorax and abdomen will be covered by red pruinescence.

Painted Skimmer dragonfly (female)

June 12, 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.

04 JUN 2019 | PNC. William County, VA | Painted Skimmer (female)

This individual is a female, as indicated by her terminal appendages. Notice her right hind wing is slightly malformed near the body. It appears the wing failed to inflate completely during emergence. The malformation didn’t impair her ability to fly.

Did you recognize the interrupted fern (Osmunda claytoniana) in the background?

Eastern Pondhawk dragonfly (female)

June 5, 2019

An Eastern Pondhawk dragonfly (Erythemis simplicicollis) was spotted during a photowalk with Mike Powell at Occoquan Regional Park, Fairfax County, Virginia USA. This individual is a female, as indicated by her terminal appendages.

Beginners beware — immature male Eastern Pondhawks are the same color as females of the same species.

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.

Skimmertime, and the livin’ is easy.

May 24, 2019

Skimmers (Family Libellulidae) — like this female Spangled Skimmer dragonfly (Libellula cyanea) — remind me of “Summertime,” a classic song from the opera Porgy and Bess.

One of these mornings you’re gonna rise up singing
And you’ll spread your wings and you’ll take to the sky

This individual was spotted during a photowalk around a small pond with my good friend Mike Powell.

21 MAY 2019 | Northern Virginia | Spangled Skimmer (female)

The last two photos are similar takes on the same pose.

Gear talk

All of the photos featured in this blog post are uncropped JPGs, that is, full resolution for the Panasonic Lumix DMC-FZ300 superzoom bridge camera (4,000 x 3,000 pixels), published “as is” straight from the camera. I tweaked the settings for in-camera processing of JPG files and I must say I think the results look good!

It’s worth noting that I always shoot/save/edit RAW photo files. Period, full stop. I have been using JPG (Fine) plus RAW (actually, RW2) while field testing the FZ300.

Deeper dive

I recently expressed disappointment and frustration with the performance of my newer Panasonic Lumix DMC-FZ300 superzoom digital camera versus my older Panasonic Lumix DMC-FZ150. After making the switch to shooting in Manual Mode, I’m pleased to report I think I’ve found a new “set it and forget it” configuration for the FZ300.

In Manual Mode, my “walking around” settings are ISO 100, an aperture of f/4.5, and a shutter speed of 1/800 s. All of the photos in this post were shot at f/4.5.

The camera features three Custom Modes: C1; C2; and C3. C1 uses all of the “walking around” settings, except for changing the aperture to f/5.6; C2 uses an aperture of f/6.3; and C3 uses an aperture of 7.1. With the mode dial set for “C” it’s easy to switch from one custom mode to another by pressing the menu button and selecting one of the three custom settings, depending upon the desired depth of field.

An external flash unit is used in Manual mode;. The power ratio is adjusted for proper exposure, depending upon the aperture: more power is necessary with a smaller aperture (larger f-stop number); less power for a larger aperture (smaller f-stop number).

As I mentioned previously, I tweaked the settings for in-camera processing of JPG files: Photo Style = Standard; Contrast = +2; Sharpness = +2; Noise Reduction = 0; and Saturation = 0.

Noise reduction can be a good thing, but NR can soften image sharpness so it’s an adjustment I prefer to make in post-processing.

Faked out!

May 13, 2019

A Blue Corporal dragonfly (Ladona deplanata) was perched on a tree alongside Wildlife Loop trail at the North Tract of Patuxent Research Refuge, Anne Arundel County, Maryland USA. This individual is an immature male, as indicated by its lighter coloration and terminal appendages.

My good friend Mike Powell and I were searching for Harlequin Darner (Gomphaeschna furcillata). At first glance, we thought we might have found our first Harlequin; after a closer look, we realized we’d been faked out by a Blue Corporal.

Another Blue Corporal dragonfly was perched on the great red spot of the planet Jupiter. Kidding! Seriously, Blue Corporals typically perch on the ground — this dragonfly was perched on a wooden boardwalk near a small pond.

The last two individuals are mature males, as indicated by their darker coloration and terminal appendages.

Predator-prey relationship?

There is some speculation that Blue Corporal dragonflies might prey upon Harlequin Darners, so Mike and I weren’t happy to see lots of mature Blue Corporals in our target search area. For what it’s worth, we hunted intensively for Harlequin Darner for hours and found only one individual; G. furcillata was described as “relatively abundant” two-to-three weeks earlier at the same location, before Blue Corporal began emerging.

Painted Skimmer dragonfly (female)

April 29, 2019

Painted Skimmer (Libellula semifasciata) is one of my favorite species in the Family Libellulidae (Skimmers). It’s hard to believe I didn’t post any photos of this beautiful dragonfly during 2018!

This individual is a female, as indicated by her terminal appendages. She was spotted near a mid-sized pond at the North Tract of Patuxent Research Refuge, Laurel, Maryland USA.

Great Blue Skimmer dragonfly (mature male)

April 12, 2019

Great Blue Skimmer dragonfly (Libellula vibrans) was spotted near a vernal pool in the forest at Huntley Meadows Park (HMP), Fairfax County, Virginia USA. This individual is a mature male, as indicated by his terminal appendages, discolored abdomen, and tattered wings.

This male has mated many times, as indicated by the scratches on his abdomen.

Males that have mated often have marks on their abdomen where the female legs have scratched them. This is especially obvious in species in which males develop pruinosity, as the pruinosity on the mid-abdomen is scratched off, and the signs are visible at some distance.
