Most of the dragonflies that I see at this time of the year—and there are a lot of them—are members of the skimmer family. This is the largest family of odonates (the insect order of dragonflies and damselflies) and includes the species most likely to be seen by a casual dragonfly observer.
When I first started getting interested in dragonflies, I focused primarily on colors—there were blue dragonflies, white dragonflies, red dragonflies, and so on. Over time I began to notice more and more differences between somewhat similar species.
Today I decided to feature photos of two dragonflies that I spotted on Thursday at Jackson Miles Abbott Wetland Refuge. Both are male, both are blue, and both are perched in a similar position. The first one is a Spangled Skimmer (Libellula cyanea). Even though it shares its blue coloration with several other species, the little white patches on the edge of the wings, known as “stigma,” are both distinctive and diagnostic. The second one is a Slaty Skimmer (Libellula incesta). It is probably the darkest colored dragonfly in our area in terms of both its body and its eyes, which sometimes appear to be almost black.
Do you see these two dragonfly species in your area? I encourage you to look closely at the ones that you happen to see and see if you can identify some of the differences. You may find yourself being drawn more deeply, as I have been, into the wonderful world of dragonflies.

Handsome young men, Mike.
Thanks, Dan. At this time of the season, they are in almost perfect condition. As we go deeper into summer, their colors will fade and their wings may become tattered–sort of like us. 🙂
I love those little black areas on their wings.
Thank you for the details, and now even I am looking for distinctive markings.
Two beauties!
A truly interesting blog. So much knowledge and patience
Such beautiful colors!
Thanks. I am always amazed at the color variety of creatures in nature, particularly dragonflies and birds.
Love the Slaty with the black stigma
