I have always admired photos of Roseate Skimmers (Orthemis ferruginea), a spectacular dragonfly species in which mature males are bright pink in color. There have been a handful of sighting over the years of Roseate Skimmers at one of the parks I visit in Northern Virginia, but until last week I had never seen one.

A little over a week ago, when I spotted the dragonfly in the first photo, I knew almost immediately that it was a Roseate Skimmer, because of the shockingly pink color of its body. Later that day and on a subsequent walk along the Colorado River in Bastrop, Texas, I spotted other Roseate Skimmers, but did not realize that was what they were until much later.

Why did I have such trouble with their identification? When it comes to dragonflies, mature males tend to be brighter in color and have more distinctive markings than their female counterparts that have drab colors that are somewhat similar across species. Additionally, immature males often have the same coloration as the females.

So, when I posted the second photo below in an earlier posting and thought is might be a Variegated Meadowhawk, I was absolutely wrong. According to some experts in Facebook groups and at Odonata Central, the dragonfly is an immature male Roseate Skimmer.

The dragonfly in the final photo is a female Roseate Skimmer that I photographed a few days ago. Note how the coloration is similar to that of the dragonfly in the second photo. How do you tell them apart? If you look closely at the terminal appendages at the end of the abdomen (the “tail”) of the two dragonflies, you should be able to see that they are quite different in shape. Most often, those terminal appendage are key in distinguishing immature male dragonflies from females.

In a few days I will be heading home from Texas. It has been fascinating to see quite a few dragonflies, some of which have been new for me. Even here, though, I suspect that the season may be coming to a close soon. Earlier in the week temperatures were in the mid-80’s (29 degrees C), but I awoke this morning to a temperature of 41 degrees (5 degrees C) and we will drop even closer to the freezing level over the next couple of days.
