Are birdhouse gourds pollinated by moths?

So I'm at the Farm, watering after dark this evening and there are all these big white flowers that catch my eye. Why are those morning glory in bloom now, I wonder? Then I see that it is not morning glory, but that it is birdhouse gourd, how cool. Hey, why is the flower in bloom at night and big and white? As I spy the almost full moon, I wonder if it is to attract moths!?

Well, I don't have the answer right now, and I have not looked up the possibility online yet either. I hung out by the blossoms for a while and saw a moth flitting around, but never saw it land.

Pretty doggone cool!
