We have a couple hummers in our yard. Animals not cars that is. A female ruby-throated hummingbird visits the red beebalm daily. She zooms in, hovers nearby, and if I am too close she zooms off. Another, smaller creature hums and hovers and flies fast among the beebalm. It is not a bee or a hummingbird, but a moth, a hawkmoth. A hummingbird clearwing (Hemaris thysbe) to be precise.
This hawkmoth is a beautiful olive and burgundy color. Its legs, antennae, and proboscis (for sipping nectar) are long. The hummingbird clearwing is a welcome sight among the beebalm, phlox, and other perennials.
