A rare time that I have seen one of these not in the air and it let me close in to take pictures of it. I did this with my camera's in-camera focus stacking feature which allows 8 shots to be combined with the camera refocusing between each shot to get a lot more depth of field than a normal single macro shot. What is really amazing is that this was done handheld. I'm still surprised it worked this well. Here is a photo of one in flight: https://pbase.com/dlgphoto/image/174270857 and also https://pbase.com/dlgphoto/image/172996318 . They are often mistaken for very small hummingbirds.
