Black Saddlebags

In a previous post about Black Saddlebags, I mentioned that these dragonflies are seldom seen perched except in the treetops. This individual hung low in the undergrowth, allowing Erika and me to get quite close at the Ritter Farm Park in Dakota County, Minnesota. We were surprised by the blue stripes on the thorax and the amount of yellow on the top of the abdomen. These markings are probably the signs of a young female. In this photo, you can clearly see the large dark splotches on the hind wings that give this species its common name.  Paulson (2011) reports that Black Saddlebags are migratory here in the north, prefer to mate near lakes, and, as they deposit eggs, are often taken by bass.

  1. This is one of the best images I've seen showing the saddlebags, Dan. Really neat!
