A perfect perch.

A young male variegated meadowhawk dragonfly, Sympetrum corruptum, found a perfect perch--a seed ball of Mexican sunflower (Tithonia) in our pollinator garden in Vacaville, Calif.

It towered over the garden and so did he.

Naturalist Greg Kareofelas, Bohart Museum of Entomology associate, University of California, Davis, has been seeing and photographing some of these migrating dragonflies in his yard in Davis as well.

"Evidently, there was a big migration of lots of these dragonflies south of San Francisco," Kareofelas noted in his Facebook post.

And apparently thousands have been spotted at Half Moon Bay. Dragonfly alert!

Variegated meadowhawks live near ponds, lakes, and swamps. They are largely tan or gray with a pale face that is tan in young males and females but becomes red in mature males, according to Odonatacentral.org. They're found throughout the United States and southern Canada; also Mexico south to Belize and Honduras. "This species may be seen on the ground more than other meadowhawks. It will also readily perch on the tips of grass stems and tree branches. It can be numerous flying over roads, lawns, meadows, marshes and ponds...It is largely tan or gray with a pale face that is tan in young males and females but becomes red in mature males."

The Bohart Museum, located in Room 1124 of the Academic Surge building on Crocker Lane, offers a beautiful dragonfly poster, "Dragonflies of California," in its gift shop. It's the work of entomologist Fran Keller (she received her doctorate in entomology from UC Davis and is now an assistant professor at Folsom Lake College) and Kareofelas, whose expertise includes butterflies and dragonflies.
