After a mishap involving salt water that killed one of my little macro flashes, I got an inexpensive adapter that takes light from a big flash and makes it into a ring flash, essentially a ring of light around the camera lens. It’s awkward and cheap, but it does create a very soft, even lighting as you can see here. The moth seems to be a spiderling plume moth, named that because the caterpillars primarily eat spiderling plants. These plants are from the same family as bougainvillea. The plume part of the name is pretty obvious, because the wings are narrow and plume-like. There seem to be at least a few species from this moth family on the island.
