The Great Imposter

The large insect photographed here (Courtesy The Treelady, Madeline Sutter, ASLA - Oriental, North Carolina) found among nectar flowers, is frequently mistaken for a hummingbird. Known as hummingbird moths, or sphinx or hawk moths, they sometimes weigh more than a hummer, can hover, and are very fast fliers. Their antennas, however, are a dead giveaway if you're close. Also, their long tongues coil under their heads.

   

These are not hummingbirds.
