Posts Tagged ‘Ischnura posita’

Some of the photos in recent postings have shown that damselflies are incredibly flexible. Normally they demonstrate this flexibility when mating with a partner.

Earlier this week I spotted this damselfly, which I believe is a male Fragile Forktail (Ischnura posita), doing a solo gymnastics exhibition. The acrobatic damselfly repeatedly would swing its body backwards (second photo) and them end up with the tip of his abdomen between his legs (first photo). What was he doing?

According to my local dragonfly/damselfly expert Walter Sanford, damselflies are quite fastidious and will often spend time grooming themselves. That is what appears to be happening in these photos.

Who knew? It is not what I would have guessed—sometimes truth is stranger than fiction. 🙂

Odonata is an order of insects that includes dragonflies and damselflies. In general, dragonflies tend to be larger and perch with their wings held out to the sides, while damselflies are smaller, have more slender bodies, and most  hold their wings over the body at rest. I try to pay attention to members of both damselflies and dragonflies, but often spend more time with the latter group, because they are easier to find and photograph.

In the interest of equality, I decided to devote today’s post to some of the female Fragile Forktail damselflies (Ischnura posita) that I have observed this past week. The three images show female Fragile Forktails in three of their main activities—perching, eating, and ovipositing (laying eggs). I have no recent shots of the mating that precedes the ovipositing, so I will leave that to your imagination for now.

As you probably noted, the coloration of these lady damselflies varies. The damselfly in the first image with the distinctive markings is an immature female. As the females age, they acquire a bluish coating that is sometimes referred to as pruinescence, which you can especially see in the second image. The third image shows a damselfly arching her long abdomen as she deposits eggs in the debris floating on the surface of a small pond.

I’m still looking for my first dragonfly of the season, but was thrilled yesterday afternoon when I spotted my first damselfly, a Fragile Forktail (Ischnura posita), at Jackson Miles Abbott Wetland Refuge. In anticipation of seeing one of these small insects, I mounted my Tamron 180mm macro lens on my camera, a lens that has gone largely unused during the long winter months in favor of my telephoto zoom lens.

Yesterday was a nice reminded of how much I enjoy using a macro lens. (To give you a sense of scale, a Fragile Forktail damselfly is about 0.8-1.1 inches in length (21-29mm).)

As I drove back yesterday from Georgia to Northern Virginia, an almost 800 mile drive (1287 km),  I stopped at a rest area on I-95 in North Carolina. Noting that there was a small man-made pond, I decided to investigate for odes and spotted this damselfly. One of the experts in the Southeaster Odes Facebook Group helped to identify this beauty as a female Fragile Forktail damselfly (Ischnura posita).

It’s a whole lot cooler in Northern Virginia than it was in Georgia and North Carolina, so I suspect that I will have to wait a month or two for damselflies and dragonflies to emerge here. With this sneak preview, I can hardly wait.

It’s still a bit early for dragonflies in Northern Virginia, but when temperatures soared to almost 80 degrees (27 degrees C) yesterday in Columbus, Georgia, I decided to see if I could find some here. I had a wonderful time exploring some of the area of the Oxbow Meadows Environmental Learning Center that is not far from Fort Benning, where I was staying.

I came up empty-handed for dragonflies, but did spot some beautiful little damselflies. Later in the spring, these will be fairly common, but after a long period with no odonates, they seem rare and exotic.

The first one looks like a Fragile Forktail damselfly (Ischnura posita), but I am not sure about the others. Several of them flew so weakly that I wondered if they had only recently emerged.

As I turned to photograph a tiny damselfly perched on an overhanging branch, it flew down to the water. Initially I was disappointed, but then I looked more closely through my camera’s viewfinder. The male Fragile Forktail (Ischnura posita) had landed on a floating leaf and had assumed a pose that made it look like he was riding a surfboard. As a bonus, I was able to capture a fascinating area of bubbles in the algae in the foreground of the image.

I haven’t taken very many damselfly photos this summer, in part because often I have been attempting to shoot dragonflies with my long telephoto lens. That lens has a minimum focusing distance of almost nine feet (2.7 meters) and it’s hard to see and focus on a tiny damselfly at that distance.

This past weekend, however, I was using my 180mm macro lens and was happy to be able to capture some images of this beautiful female Fragile Forktail damselfly (Ischnura posita) during a trip to Lilypons Water Gardens in Adamstown, Maryland.

Damselflies are really small, but they pack a lot of beautiful details and colors into that tiny package. This particular species is special to me this year, because way back in April a female Fragile Forktail was the first damselfly that I spotted this season and presented in this posting.
