Posts Tagged ‘female Ashy Clubtail’

Earlier today I did a posting that discussed perching behavior and featured shots of two male Ashy Clubtail dragonflies (Phanogomphus lividus) that I had photographed last Thursday on a rocky area along a stream in Prince William County, Virginia. As I was going through my shots from this past Saturday, I came upon this image of a female Ashy Clubtail that serves as a nice complement to the photos in the earlier posting.

The most obvious differences is that this female dragonfly chose to perch on this interrupted fern that was much higher off of the ground. Note, however, that like her male counterpart, she is perching horizontally and not grasping onto a stalk or a branch, as some other dragonflies are prone to do. This image gives you a partial view of the terminal appendages at the tip of her abdomen (the “tail”) that make it clear that this is a female. If you compare those appendage with the same area of the males, you may be able to tell that they are different.

There are other ways to tell the gender of dragonflies, but I will save those explanations for a later posting, or leave them to my dragonfly-hunting friend Walter Sanford, who is much more of an expert on this topic than I am.

I spent most of my time looking for birds during a trip last week to Occoquan Bay National Wildlife Refuge and I managed to capture the images of the bald eagles that I featured yesterday. The day had started off cool and overcast, more suitable for birds than for dragonflies, but when the sun finally broke through in the late afternoon, I decided to swing by a small pond on my walk back to the parking lot on the off chance that I might find a dragonfly.

My hunch paid off when I spotted this female Ashy Clubtail dragonfly (Phanogomphus lividus) perched low to the ground. At that moment I had my Tamron 150-600mm lens attached to my camera and that presented a challenge, because its minimum focusing distance is 8.9 feet (2.70 meters), so I had to back up. At that distance it is hard to locate and focus on a subject that is only 2 inches (50 mm) in length. Fortunately I have been in this situation before and I steadied myself, focused manually, and captured the first image before the dragonfly flew away.

Having established that there there was at least one dragonfly in the area, I switched to my Tamron 180mm macro lens, my preferred lens for dragonflies, and continued my search. A few minutes later I spotted another female Ashy Clubtail when it flew up into some low hanging vegetation and I captured the second image. There is a good chance that this was the same individual that I photographed earlier—both of them are pale in color, suggesting that they had only recently emerged from their larval state.

As I moved a little closer for the final shot, the dragonfly closed its wings overhead, reverting briefly to an earlier stage when it was in the process of emerging. I have seen this happen before when a newly emerged dragonfly, sometimes referred to as a teneral, flew for the first time and its wings were still in a very fragile state. At this point, I decided to stop shooting, fearful that I might spook this newly emerged dragonfly into flying at a time when she clearly needed to rest.

If you are unfamiliar with the amazing process that a dragonfly goes through in transforming itself from a water-dwelling nymph to an aerial acrobat, check out my blog posting called Metamorphosis of a dragonfly that documents the entire process in a series of photos.
