This Twelve-spotted Skimmer (Libellula pulchella) was parked just off the path around 730pm, so I think it was roosting for the night. The black markings looked velvety in the light.
This is a mature male. If you counted the white spots, too, he would be a twenty-spotted skimmer. To matters more confusing, this species used to be known as the Ten-spot… can you guess why?

Only the white spots count?
Seems they were counting the markings at the base of the wings as one going across the thorax, and hence 2 “spots” instead of four.
Ah! Higher math was always beyond me!
