Making macro-photographs of wasps on the loose is certainly a pretty exciting undertaking! Good luck! I approached the problem by placing them in a confined space and then made them take their own picture so to speak. I found that trying to stalk them as the flitted about was much too difficult. I also wanted them in flight and with relatively sharp wings. I also found my reaction time was too slow to ensure sharp pictures at macro scale due to small focusing errors. So, as they flew from one side of a covered fish tank to the other every so often they passed through crossed laser beams (camera on tripod was focused where the two beams crossed) and this would start a chain of events that eventually caused a Vivitar 283 operating at 1/32nd power to flash and the record to be made. Since the process was automatic I left the set up while going to lunch or overnight and next visit just checked the frame counter to see if any pictures had been made. The system worked quite well! andy
