Thank you Morris and Dave. I have spent the past four summers working on laser traps for birds and insects.
I use a laser trap. Cameras are not fast enough to capture insects in flight, it takes too long for the shutter to react. The alternative is a high speed shutter which keeps the camera dark, in Bilb mode, but the shutter open. The laser trap triggers the high speed shutter and flash. In this case I used four Nikon SB 910 flashes set to 1/128 power. This provides an effective shutter speed of about 1/40,000 second. The camera, in Bub mode, takes a picture every minute but the high speed shutter and flashes only fire when the laser is tripped. So photo 1 the shutter fired after 57 seconds, #2 at 3 seconds. Over 5 hours I get 300 shots with maybe 5 or 6 actual images when the laser fired the system.
