I am soooo glad I found this website!! My 5 year son found these bugs in our pond. I have no idea what it is. So I could not tell him what it was called. We live in northwest (panhandle) Florida, in a city called Crestview.
These are Dragonfly Naiads. In the immature larval form, they are aquatic. They will survive in an aquarium and catch small insects, tiny fish and tadpoles. Eric Eaton provided this further classification: ” The dragonfly nymphs are some kind of skimmer dragonfly, family Libellulidae. The globe skimmers, genus Pantala frequently lay eggs in ridiculously small ponds, even fountains, so that would be my guess.”
