Top 10 Photos of 2015
Voting for my “Top 10 Photos of 2015” will close at 12 midnight EST on 01 January 2016.
Winter Meadowhawk dragonfly
A few Autumn Meadowhawk dragonflies (Sympetrum vicinum), jokingly referred to as “Winter Meadowhawk dragonflies” in a recent post, were observed near the terminus of the Hike-Bike Trail at Huntley Meadows Park. This sighting sets a new late-date for this species at Huntley Meadows Park. 01 January is the “official” late-date for the Commonwealth of Virginia.
This individual is a male, as indicated by his coloration and terminal appendages.

As the story is told, a reporter asked Willie Sutton “Why do you rob banks?” “Because that’s where the money is,” Willie answered. So when people ask me why I go to the remote locations in Huntley Meadows Park, I answer “Because that’s where the undiscovered species of odonates are.”
There are undiscovered species of odonates at the remote places in the park, in part, because fewer people go to the more difficult to reach locations. Also, the remote locations are often where the “habitat specialists” are found, in contrast with the “habitat generalists” that inhabit the central wetland area.

It’s the time of year for reflection upon the past year. This is part one in a three-part series: part two will highlight New discoveries in 2015; part three will showcase my Top 10 Photos of 2015.
Several of my photographs received special recognition during 2015.
- Chesapeake Explorer – National Park Service Web portal for exploring the Chesapeake Bay region
- Vernal Pools are Wet and Dry – signage facilitating informal science education at a new park in the Town of DeWitt, New York
- Argia, Vol. 27, Issue 4, “Parting Shots,” p. 31
The December 2015 issue of Argia, The News Journal of the Dragonfly Society of the Americas, features one of my photographs of a Roseate Skimmer dragonfly (Orthemis ferruginea) that I discovered on 23 September 2015 at Huntley Meadows Park. Roseate Skimmer is extremely uncommon in Virginia: there are only three other confirmed records of this species in the state. See Roseate Skimmer dragonfly (male) for more information and photos of this handsome dragonfly.
Tech Tip: Apple “Preview” was used to extract one page from the December 2015 issue of “Argia.”
Sidebar: “Argia” is a genus of damselfly, commonly known as “dancers.” For example, Variable/Violet Dancer (Argia fumipennis) is commonly found along streams in Northern Virginia.

Painted Skimmer dragonfly (Libellula semifasciata) is another species that should be added to “Top 10 Most Beautiful/Handsome Dragonflies of the Mid-Atlantic USA.”
These two individuals are males, as indicated by their terminal appendages. They are perching in a small meadow near a vernal pool/small permanent pond.

I’ve said it before — when you’re making a list of the “Top 10 Most Beautiful Dragonflies of the Mid-Atlantic USA,” don’t sleep on the female Blue Dasher dragonfly (Pachydiplax longipennis). I think it’s easy to overlook their beauty because Blue Dasher is a relatively common species of dragonfly — males seemingly more common than females — but I think the females are uncommonly attractive.
The individual shown in the preceding photo is a female, as indicated by her coloration and terminal appendages. Blue Dashers display sexual dimorphism; terminal appendages may be used to differentiate females from immature males.

A distinctive Great Spreadwing damselfly (Archilestes grandis) was spotted at a remote location in Huntley Meadows Park (HMP). This individual is a male, as indicated by his coloration and terminal appendages. I nicknamed this male Great Spreadwing “Bendy Straw” because of his slightly malformed abdomen.
Notice the bend in his abdomen at the boundary between segments seven and eight (S7 and S8). Remember that all dragonflies and damselflies have a 10-segmented abdomen, numbered from front to back.
I met “Bendy Straw” on 11 October 2015; I never saw “Bendy” again, although Mike Powell photographed him on 16 October.

I discovered a new species of dragonfly: Winter Meadowhawk (Sympetrum antifreezium). Kidding!
Winter is defined in two ways: astronomical winter begins on the date of the December Solstice (around 21 December) and ends on the March Equinox (around 21 March); meteorological winter includes the months of December, January, and February. Although astronomical winter hasn’t begun (as of this writing), meterological winter began on 01 December. So I took the liberty of jokingly renaming the last species of odonate still flying during the third week in December (in Northern Virginia): Autumn Meadowhawk dragonflies (Sympetrum vicinum).
I spotted 10s of Autumn Meadowhawks at two locations in Huntley Meadows Park (HMP): most of the dragonflies were seen perching along the boardwalk that goes through the central wetland area; one individual was spotted near a vernal pool/small permanent pond at a remote forested location in the park.
Males
The first two photos in this gallery show two males, as indicated by their coloration and terminal appendages.
Mating Pair
The next photo shows a mating pair in tandem: the male is on the lower-left; the female on the upper-right.
Female
The last two photos show a female, as indicated by her coloration and terminal appendages.

Editor’s Note: 16 December establishes a new late-date for Autumn Meadowhawk dragonflies at Huntley Meadows Park. 01 January is the “official” late-date for the Commonwealth of Virginia.

Rudolph the Red-nosed Skink
Had a very shiny nose
And if you ever saw it
You would even say it glows
This individual is either a Broad-headed Skink (Plestiodon laticeps) or an adult male Common Five-lined Skink (Plestiodon fasciatus); it is probably the former, as indicated by a field mark used to differentiate the two species.

A Slaty Skimmer dragonfly (Libellula incesta) was spotted at Huntley Meadows Park. This individual is a mature male, as indicated by its coloration and terminal apppendages. A male Blue Dasher dragonfly (Pachydiplax longipennis) is shown in the background.
These two males were rivals, competing for one of two perches overlooking a wetland pool. I was amused by the smaller Blue Dasher’s aggressive behavior as he buzzed the larger Slaty Skimmer repeatedly, trying to recapture the prized perch he occupied before the Slaty showed up.
