Boy, did I dread the sight of those things when I had a garden! (They fly in the daytime, and -- if unlucky -- you may see them often.) I considered them my major insect enemy.
Unlike some insects that just eat leaves or even parts of the fruit, it doesn't take but one of these to kill a large and luxuriant plant. They lay tiny hard-to-spot eggs near the base of the stem. The grubs live inside, and typically girdle it, killing the entire plant.
Very interesting critter. Nice shots. Good commentary. Don't recall having seen one. It's a clear wing moth, similar to the one I posted 1689.1 but definitely not the same species. I'm learning how many different clear wing species there are.
