Hey Ken,
The cultivar "Luna Moth" is not so very different from "White Butterfly"... a bit less weedy looking, more stout leaves and flowers are more fleshy and full. When I order tissue cultured Ginger, most often this is the variety that is offered for White Butterfly type.
Yes, those Sphinx moths like mine too...along with my 4-o'clocks in the evening. A lot of the Sphinx moths we see here are the end result of Tomato Horn worms. Yuck, lol. I enjoy their activity I the garden. One night I took a flashlight out to the yard to run off some varmit that was marauding my freshly planted garden. I happened to hit the large patch of 4-o'clocks with my light and saw HUNDREDS of glow-in-the-dark eyes. Reflected light just like a cats!
