A moth found its way into my house. This morning while brushing my teeth I noticed the moth in my cup. I thought it was dead

So I emptied him out of the cup into my palm. To my surprise he started moving, he was alive! I apologized for disturbing him and told him I'd escort him outside. He started flapping his wings but wasn't able to lift off my palm. By the time I got outside I thought to put him in a pot with a plant and a little bit of water- maybe that'd help him gather his strength? Instead he finally flew off my hand, a bit wobbly though he tumbled himself about and landed on a cushion. I went down to scoop him up, thinking he needed to regain his strength... but he had completely disappeared. I looked around, no sign of him flying nearby- and I looked under the chair, he wasn't there either.
I forgot the significance of the moth and am bumping this thread as I re-discover.
