My OH has an overwhellming and irrational terror of moths, if one enters the room, however small, she leaves.
Some years ago we had an Elephant Hawk Moth in the living room one evening, the only light was the TV in the opposite corner.
I noticed it and said nowt, she walked through a couple of times with washing.
I then asked her if she had noticed the large moth, "what large moth" she replied.
That one up there, she looked and to my surprise, no reaction.
Silly thing is I had to work pretty hard to convince her it was a moth, its wings were completely furled and it looked as though I had stuck a sausage at the top of the wall.
However once I put the main light on, it started to move around the wall a bit, the wife left rather quickly and refused to come downstairs until I had, gently, captured the poor beast for release outside.
Even sillier thing is, despite her near rabid terror, she had to watch me release it outside to convince herself it was gone.
