This magnificent moth, which I believe is an owl moth, complete with eyes in the back of his head, landed on my kitchen window last night so I snuck out and managed to get a photo of him and he was more impressive from outside than he was from inside.
I estimate the wing span to be 10cm (those lace panels are 15cm wide. I took the tape measure too but he wouldn't keep still!). He was so heavy he kept sliding down the window and had to keep repositioning himself. Some geckos were circling so I turned out the light early and hoped he got away.
