Hummingbird Hawkmoth

Walking back to my car after work I had to stop in my tracks when I saw this little beauty fluttering about over these flowers.
The Hummingbird Hawk Moth is a day-flying moth with a wingspan of about two inches.
 It has a brown, white-spotted abdomen, brown & orange wings. 
It is a very fast flyer & expert at hovering. 
The wings beat so fast that you can hear a quiet hum & can be seen as a blur.
