Of course, I brought along my humble black light and my sheet, figuring there would be a good spot to set it up outside out rented guest house. The best option turned out to be replacing the bulb of their back deck light with my black light bulb, and draping my sheet just beneath it.
This is it. Tacky, but effective.
There were plenty more moths nearby, but not on the sheet.
I have several shots of these lovely green geometrid moths. You can see them, and some other bug shots that I may not necessarily post here, on my Flickr set.
