Moth Invasion

Boo was barking and barking at the window last night - it was a little scary. When I checked it out I saw this moth on the wall. It was GIANT!! I chased it around with a plastic bag (held open to catch the moth) and finally it landed and I scooped it up and took it outside. That thing was so big and pretty - it looked fuzzy and was the size of my open hand. I'm wondering what attracted it to my yard, what it will turn into, and if it got away safely since it seemed to fly a little strange and the bottom of one of it's wings looks damaged (I didn't do it)
