This is an elderly male Widow Skimmer. Note the worn, torn wing edges from weeks of flying and constant encounters with branches,thorns and maybe even birds. The white marks on the abdomen and shoulders of thorax were once black. He’s obviously doing fine because he is eating a tiny green beetle!
Compare to a young male Common Whitetail. Undamaged wing edges. Thorax and abdomen unmarred. Notice the different colors and patterns on the different dragons!
Have you seen many dragonflies this summer? We think there are a lot this year!
