Hummingbird Moth

This was my first spotting of one on these neat moths. They hover over flowers the same way a hummingbird does & gets nectar with its long proboscis. It doesn't sit on a flower like a butterfly does. Their bodies can be up to 2 inches long. This one was an inch long with a wing span of about an inch & 1/2. The wings have scales on them, but apparently the scales fall off & that makes their wings appear transparent.
