Oh, it's a Luna Moth! I haven't seen one of those in over 20 years! That really makes me think of my childhood in the woods of Maine, we'd always see them. I don't think I've seen any anywhere else since then. I love those, they're so pretty and sweet. I used to sit on my porch at night and they'd land on the house by the spotlight and I'd just sit and stare at them in awe. Thanks for reminding me of a fond childhood memory.
Incidentally, the ones I had in the woods of Maine were HUGE. I don't know if they are all that big or not, and it's hard to tell from the OP's pic, but I'm talking like the size of my fully spread out hand! Just beautiful.
Yeah, I kind of thought they all were, but I've really never seen them anyplace but there, so I wasn't sure. Also, in those woods we had some weird *mutant* gigantic things. Extra big moths, extra big frogs; we discovered a lot of giant sized stuff deep in those woods!
This is the first one i've ever seen here. Hubby called me in the room asking me if I wanted to catch a huge butterfly for my daughter. I was so excited to see what it was, so I let it in to take a few pics, then let it back out. Now I'm going to be watching for them more often.
