I have a couple of field guides to dragonflies and damselflies. Still, it can be difficult to identify the insects from photographs. This one looks like a familiar bluet, Enallagma civile.
That seems the closest, anyway. I think this damselfly is still a little immature, and will darken with time.
Dragonflies and damselflies can be difficult to identify positively.

ANother lovely insect shot. Have the Odanata all been on time in Iowa? As with most other natural phenomena they were late in the UK this year due to a very cold springtime. But they’re in abundance now.
Odonates were delayed somewhat but not to the extent that butterflies were. They have been about as numerous as most years, unlike the butterflies whose numbers have been way down.
