Hummingbird moth?

Hello bugman,
This moth flew into my friends sun room last week. It was pretty big, about the size of a hummingbird. It sounded like one, too. I was thinking it could be some type of hummingbird moth, but I’m not sure. Please let me know what type of bug this is. Thanks. 🙂

Hi Danielle,
Moths in the family Sphingidae are commonly referred to as Hawkmoths or Sphinxes, and Hummingbird Moths are a common name for the Clearwing diurnal moths in the tribe Dilophonotini, a subcategory of the Sphingidae.  Your moth is a Nessus Sphinx, Amphion floridensis, which despite its name, has a much greater range than just the state of Florida.  The Nessus Sphinx is also a diurnal species and it is frequently mistaken for a hummingbird, as are many of the Sphinxes, especially when they hover near flowers gathering nectar.  You may read more about the Nessus Sphinx on Bill Oehlke’s awesome website.
