I decided to test out the video function last night and was impressed with the results. It shoots in HD, so I can actually get some quality video out of it. The subject I turned to was a firefly in the genus Photuris that seemed to be on its way out the door. I grabbed my hand lens and recorded a short video of it flashing, which you can watch below. It was interesting to watch up close, which I had never done before.
Fireflies produce light via a biochemical reaction utilizing luciferin, luciferase, ATP, oxygen, and magnesium. This happens in the last few segments of the abdomen. Watching it up close I noticed many small sparkles of light before the big flash, who knew?
