Here are a couple of photos I took at the third pond in Agua Caliente Park. I know very little about insects, and I haven't been able to identify these dragonflies. I'd be very pleased to learn what they are.
The first one seems similar to a Neon Skimmer, but isn't as bright as those I've seen pictured on the Internet.
I retired from the University of Arizona, where I coordinated distance learning. New enthusiasms include learning about digital photography and photoprocessing, archaeology, theatre, and observing the natural world around me.
