Male Lestes alacer
I had been to this park a few times before but never to the pond, which we just made it to as the light faded. Mostly Enallagma civile, Ischnura posita with a couple Anax junius and I saw this individual male Lestes alacer.
Though the pond looked like a giant puddle housed in some construction or cement debris there were a few small twiggish trees growing inside and the brush around the area was very abundant, a great support/cover for insects.
