I found this Luna moth in the parking garage yesterday morning as I was biking in to work. I was worried that someone had hit it with their car and it was injured, but it was just hunkered down for the day. This is one of the prettiest moths. I would have assumed they are pretty rare since I have never seen one before, but Wikipedia says they are common but are rarely seen because as an adult they only live a few days and are mostly out at night. Based on the pictures there I think this is a female.
Can you imagine all of the effort it takes to make the biological conversion to this, only to wear the wings and color for a few days? Or that the adult form moth doesn't have a mouth and so doesn't eat anything, just existing to mate, avoid predators and then die of starvation?
