Caught this little guy doing his work last Sunday at a friends house. I had never seem one of these in my life. He said it was a hummingbird moth. It was very small (only about 1.5 inches long) and flew and resembles a hummingbird so I guess I believe him. Difficult little bugger to catch! As soon as all the kids went back to playing in the yard elsewhere it got a lot easier though Shot with my 10D handeheld, 550EX Speedlight, Sigma 24-70mm f/2.8 EX @ 70mm and f/4, 1/250, ISO-400.
