This beautiful Diarsia esurialis moth was attracted to an outdoor lamp I set up at midnight to lure moth's from the forest a few feet away. My total setup and wait time for capturing moth's by 40 watt lamp light was an hour before the moth's settled down enough to land near the lamp glow. I also tried a florescent bulb and lamp. This moth was not attracted by the florescent bulb,preferring the 40 watt bulb and possibly the associated heat of the bulb. Once contained I took my photographs indoors under diffused and bounce lighting. I used a white coffee filter as background and to diffuse light effects to capture the Moth's unique color and design. I am amazed at the beauty of this moth viewed from my camera lens.
