It looks like a damselfly. That’s as close as I can guess. I am sure one of the experts here can tell you.

Yes, damselfly. Related to the dragonflies, but nearly all are smaller. Note that damselflies perch with wings folded; dragonflies perch with wings open.

But then you already guessed correctly, as "dancer" is the common name for one genus of damselflies.

Thank you for that information, The Logician LLC! Perhaps this is a baby since it seems quite small even for a damselfly.

No baby-size damsel or dragon flies. They final molt from nymph to adult at full size. There is always a variation of adult size per insect species, but the variation is often less than 2:1 or even 3:2. Insects that emerge from a pupa (includes cocoons) come out as full-sized also. Grasshoppers are an insect that look very similar from nymph to adult stages, so baby grasshoppers would be a reasonable term. No baby beetles, either. There can be a large gender difference in size for some species.
