Did try this experiment last year with a 35mm camera with a wide angle lens and 400 speed Fuji 400 Superia open for about 2-5 minutes. I was a little underwhelmed at the results but did manage to capture a images of the glowey buggers doing them loopdiloops of love.
The wide angle compressed the shots, so the already small flight path got compressed even more on a small film format.
It was fun all the same being in the meadow together with these little sugar pixies and witnessing their 2 weeks of airborn freedom as they rejoice from emerging from their pupae stage from underground for 2 years.
However the poor buggers starve themselves to death during the process to pass their torch along, and this is really a tragedy. If they only knew how to eat.
On top of that, there are sneaky ambush fireflies, from what I hear in the latest scientific firefly research, that attack/canabalize unsuspecting male flashers.
So mayhaps perchance this summer I'll take out the RZ and see if I can get closer in on their flight patterns some how.
