Hummingbird Clearwing Moth.
I love watching these creatures at work. They are almost constantly in motion, never landing on flowers like bees and butterflies, and moving quickly between different flowers. I’m surprised these phone pictures came out so well. Although the moth is throwing its own shadow over its legs, there are bits where you can see that the legs are white, which nails down the species identification.
Unlike most moths, these are diurnal. There were a few working the bumblebee heaven of Monarda behind the Visitor Center at Great Swamp NWR. By a nice coincidence, at least two hummingbirds were dipping into a feeder on the other side of the center.
Thank you for posting these beautiful photos from your phone!! I live just west of Baltimore and see these moths on my Virginia Trumpet vine often.
