Just looked this one up. It can have a wing span of up to 6 1/4 inches. There are several pecan trees and sweet gum trees near the house that are actual hosts to these loverlies.We get butterfly moths around here. And these. This one I saved from a spider web View attachment 2813479

And speaking of pecan trees. Last year I fertilized both the pecan trees near the house. They both produced an abundance of 'nuts' but half were still bad. I didn't bother to fertilize them this year and lo and behold, while I was out spreading more sevin around with the spreader I found nuts already falling from the tree in back of the house. It produces small pecans, and wouldn't you know it, every one I picked up had been munched on my squirrels and they were all good. Maybe I'll have a decent crop this year.
