the long proboscis of the hummingbird hawk-moth

Here is a good image of its very long proboscis used to collect nectar from flowers while keeping a distance from the flower without landing on it. They mimic hummingbirds. 1/800 sec f/11 Its wingbeat is very fast; an exposure speed of 1/2000+ would have been needed to freeze its movement. Next time I encounter one, I will use 1/5000 sec. To maintain the same exposure, going from 1/800 s to 1/5000 s requires opening about 2.64 stops, which gives an aperture close to f/4.5.
