Astias luna

Yep, Judy took photos of these two Luna moths on the window screen in front of the house.

Adults emerge from their cocoons in the morning. Their wings are very small when they first emerge and they must enlarge them by pumping bodily fluids through them. During this time, their wings will be soft and they must climb somewhere safe to wait for their wings to harden before they can fly away. This process takes about 2 hours to complete. The Luna Moth has a wingspan of 8–11.5 cm (3.1–4.5 in) with long, tapering hindwings, which have eyespots on them in order to confuse potential predators. Although rarely seen due to their very brief (1 week) adult lives, Luna Moths are considered common. The adults do not eat or have mouths. They emerge as adults solely to mate, and as such, only live approximately one week. They are more commonly seen at night.
