Sphinx Moths are easily confused by many people with hummingbirds and are also commonly called Hummingbird Moths due to their flight. Their wings are in constant motion even when feeding from flowers. The White-Lined Sphinx Moths range from 2.5 to 3.5 inches in size. With the constant wing motion it's difficult to see the details of these moths so the photos were taken with a fast shutter speed. The last four photos were taken at a slower shutter speed which is closer to what your eye would see when spotting them in the field.
