Opening my hut one morning I found a rather large moth. We left the door open so she could fly out after dusk. Around midnight she was still there, however. After two days I got concerned, especially as I found her perched against the window, so we build a butterfly shelter for her. As I gently got her from the window, she just let herself fall on the piece of bark underneath, like a sleeping kitten. We moved her to the shelter next to the hut and put her safely inside.
