Just as all lady bugs aren't ladies, all widow skimmer dragonflies aren't female.
A mature male Libellula luctuosa, aka “Widow Skimmer," (as identified by Bohart Museum of Entomology associate and dragonfly expert Greg Kareofelas), recently delighted us with a visit to our Vacaville pollinator garden. He perched on a bamboo stake and appeared to be considering his fast-food menu--leafcutter bees, sweat bees, hover flies, mosquitoes. Hmm...decisions, decisions!
Mr. Widow Skimmer was probably not expecting the unexpected--a strong gust of wind flapped his wings over his head! Talk about having bad hair day...
What drew us to him--besides the wind!--was his steel blue coloring and his broad wing bands. Look closely and you can see his three pairs of black legs. They catch prey with their legs and then use their "fangs" to raise it to their mouth.
"The species name means sorrowful or mournful, perhaps because the wings of both male and female seem to be draped in mourning crepe," observes BugGuide.Net. They're "found across most of the United States except the Rocky Mountain region. The range continues southward across the Mexican border. The widow skimmer has been reported from four Canadian provinces: Manitoba, Ontario, Quebec, and Nova Scotia."
How did Kareofelas know it was a mature male, recently mated? Well, when they reproduce, they form a wheel or heart shape (the process of reproduction is known as "in tandem"). Kareofelas saw the marks on the male's abdomen where the female clasped the male.
"Mature male," he said.

Big Red visited us for four consecutive days.
The red flameskimmer dragonfly, Libellula saturata, zigged and zagged into our pollinator garden in Vacaville, Calif. and perched on a bamboo stake for five hours at a time.
Occasionally, he'd hunt--lift off and grab a bee or other insect--and return to the stake to eat it.
Meanwhile California scrub jays nesting in our cherry laurel hedge eyed him. Hmm, there's lunch! And there's lunch having lunch!
Big Red knew they were there but paid no attention to them. He was more interested in the pollinators in the catmint.
He didn't seem to mind us. We eased toward him, about five inches from him. He seemed to know we weren't predators, but photographers.
According to Nature's Notebook (Connecting People with Nature to Benefit Our Changing Planet):
"This species occurs in most states in the western half of the United States from Montana to Oregon, south to southern California, east to Texas, and north through Oklahoma, Kansas, and Wyoming. There are outlying records in Missouri and South Dakota and a disjunct population in Houston, Texas. The species also occurs in northern Mexico (Baja California, Chihuahua, Coahuila, Nuevo Leon, Oaxaca, and Sonora)."
"This species is typically found near warm water ponds, warm, slow streams, lakes, ditches, and hot springs- particularly in the northern part of its range. In Idaho, it occurs in high elevation deserts."
We provided the fish pond and the pollinator garden. And the bamboo stakes...
