The Hover fly is one of the more favourable inhabitants for any garden, as it preys upon pest insects. The Hover fly will perfectly suspend itself, silently looking where its next pollen search will be. It is this stationary position, which makes it a good subject to photograph.
You will need a fast shutter speed to capture the insect in flight. It is also useful to have a high iso setting to widen the depth of field range and increase the amount of detail captured.
There is approximately 6,000 species of Hover flies and wherever there are flowers you are likely to find them. This makes them perfect subjects to practice motion macro photography, as you only have to go into your garden to see them.
