Attracted to mercury vapor and ultraviolet lights

It had rained for several days before and the night was moonless, dark, cloudy, and humid. Initially, a pretty decent amount of insects were showing up at my sheet. I usually keep both my mercury vapor and ultraviolet lights on, but on that night, at 9:00 PM, I decided to try Steve Lingafelter's advice to turn off the MV light for 15 minutes while leaving the UV light on. It wasn't even 5 minutes after that and my sheet was completely covered with insects. Although I had brought an excess of plastic vials to avoid mixing too many bugs in the same container, I quickly ran out of vials and had to leave behind many large moths. It was the best night ever blacklighting for bugs. Now I plan to consistently run the MV light in cycles to improve my catch.
