Time to mate (Fall 2017)

October 11, 2017

I speculate Blue-faced Meadowhawk is an arboreal species of dragonfly that returns to the ground/water when it’s time to mate.

A mating pair of Blue-faced Meadowhawk dragonflies (Sympetrum ambiguum) was spotted near a drainage ditch alongside a vernal pool at a remote location in Huntley Meadows Park, Fairfax County, Virginia USA. This pair is “in wheel“: the male is on top; the female on the bottom. The female is a heteromorph, as indicated by her tan coloration.

All dragonflies and damselflies have a 10-segmented abdomen, numbered from front to back: male dragonfly secondary genitalia, called hamules, are located in segments two and three (S2 and S3); female genitalia in segment eight (S8). Dragonflies form the mating wheel in order for their genitalia to connect during copulation.

Big Bluet damselfly (mating pairs)

September 3, 2017

Hundreds, if not thousands, of Big Bluet damselflies (Enallagma durum) were spotted on 30 August 2017 during a photowalk along Deephole Point Road at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

A mating pair of Big Bluet was spotted “in heart.” The male is on the upper-right; the female on the lower-left.

Big Bluet females are polymorphic, including a blue morph and brown morph. The female in this mating pair is a blue andromorph.

I photographed the following male because he was perching at the right height for me to take the shot while standing. I took one photo before he flew to another perch, closer to the ground.

30 AUG 2017 | OBNWR | Big Bluet (male)

As it turns out, the single male led me to another mating pair of Big Bluet that I hadn’t noticed!

The female in the preceding mating pair is a brown heteromorph. Color is a highly variable field marker, and describing color is subjective. In my experience, the heteromorph female Big Bluets native to Northern Virginia are light tan to light olive drab in color.

Banded Pennants (mating pair, in wheel)

August 8, 2017

“In wheel”

A mating pair of Banded Pennant dragonflies (Celithemis fasciata) was spotted at Mulligan Pond, Jackson Miles Abbott Wetland Refuge (JMAWR), Fairfax County, Virginia USA. This pair is “in wheel.”

“Insex”

In a recent blog post, I mentioned that I used to photowalk the boardwalk at Huntley Meadows Park frequently. In deference to the many women and children who visit the park, I coined the term “insex” (sounds like “insects” to the uninitiated) as a family-friendly way to alert my fellow odonate hunters/photowalkers that I heard/saw a mating pair of dragonflies.

More often than not, I hear the clatter of wings before I see a mating pair. When I hear that unique sound, “insex” is the code word I use to give people a heads-up to search for the noisy couple.

In this case, the male Banded Pennant made a silky-smooth, soundless hook-up with the female. I had been watching the female oviposit along the shoreline of the pond while a male was hover guarding her. The fact is, I’m not sure whether he was actually hover guarding or an interloper waiting for an opportunity to grab the female. Either way, I was able to shoot just two photos of the mating pair before they flew in wheel to the top of a nearby tree.

Blue-faced Meadowhawks (mating pair)

March 27, 2017

A mating pair of Blue-faced Meadowhawk dragonflies (Sympetrum ambiguum) was spotted near a vernal pool at Huntley Meadows Park (HMP). This pair is “in wheel“: the male is on the upper-right; the female on the lower-left.

There were noticeably fewer Blue-faced Meadowhawks at this location than in past years. It’s reassuring to see this pair doing their part to ensure perpetuation of the species.

Slaty Skimmer dragonflies (mating pair)

March 7, 2017

Odonates (dragonflies and damselflies) are aquatic insects that spend most of their life as larvae that live in water; this stage of their life cycle can last from a few months to a few years, depending upon the species. Finally, they emerge from the water and metamorphose into adults in order to reproduce; their offspring return to the water and the cycle begins again.

A mating pair of Slaty Skimmer dragonflies (Libellula incesta) was spotted at Painted Turtle Pond, Occoquan Bay National Wildlife Refuge (OBNWR), Prince William County, Virginia USA. This pair is “in wheel”: the male is on the upper-left; the female on the lower-right.

Multicolored Asian Lady Beetles (mating pair)

A mating pair of Multicolored Asian Lady Beetles (Harmonia axyridis) was spotted near Mulligan Pond at Jackson Miles Abbott Wetland Refuge (JMAWR), Fairfax County, Virginia USA.

When I looked closely at the preceding photo during post-processing, I noticed the face of the two beetles is colored/patterned differently. That seemed odd to me — I thought there might be an interspecies breeding thing going on here. Turns out that’s just the way it is.

The different pattern on the pronotum isn’t odd at all. They are Harmonia axyridis, the Multicolored Asian Lady Beetle, and there are hundreds of different color morphs. Source Credit: Natalie Hernandez, one of many helpful members of the BugGuide Facebook group.

Autumn Meadowhawk dragonflies (mating pairs)

January 30, 2017

While we’re doing that mating pairs of insects thing, let’s continue the theme with photos of two mating pairs of Autumn Meadowhawk dragonflies (Sympetrum vicinum) spotted near a vernal pool at Huntley Meadows Park (HMP). Both pairs are “in wheel.”

Couple No. 1

The male is on the upper-right; the female on the lower-left. Notice the male dragonfly is using his front legs to groom his eyes and face, while mating. Hey, you want to look good when hooking up!

The photo is cropped slightly in order to remove a few distracting elements near the edges of the photo. In my opinion, nothing says “Autumn Meadowhawk” quite like a photo showing the dragonflies perching on autumn-colored vegetation.

Couple No. 2

The male is on top; the female on the bottom.

The preceding photo is full-frame (4,000 x 3,000 pixels), giving the viewer a sense of how close I was to the dragonflies. This image — showing the dragonflies perching on tree bark — complements the coloration of the Autumn Meadowhawks but doesn’t convey the same sense of the season as the first photo.

Pearl Crescent is a common species of butterfly that is abundant at many of the wildlife-watching locations I visit. Although I’ve seen many Pearl Crescents, this is the first mating pair I’ve seen/photographed.

Blue-faced Meadowhawk mating frenzy

December 8, 2016

Old Colchester Park and Preserve (OCPP), Fairfax County, Virginia USA is one of a few places in Northern Virginia where Blue-faced Meadowhawk dragonfly (Sympetrum ambiguum) is known to occur. OCPP is located near Mason Neck West Park.

More than ten mating pairs of Blue-faced Meadowhawks were spotted at a small vernal pool in the park; the pool was almost completely dry on the day of my visit.

Andromorph females

Some species of dragonflies, such as Blue-faced Meadowhawk, display sexual dimorphism; females are polymorphic for a smaller subset of those species. Andromorph females are male-like in color; heteromorph females are duller in color than males.

Andromorph female Blue-faced Meadowhawk dragonflies, like the ones shown below, are less common than heteromorph females. Andromorphs have a red abdomen with black rings, like male Blue-faced Meadowhawks; unlike males, most female faces are tan and their terminal appendages look different than male appendages.
