Here is my interpretation:
A woman 'traps a moth', meaning she found someone to trick, but he is genuinely in love with her.
She builds an 'atrium', I don't think he means what spoofehness is saying (just my opinion). I think he means something similar to an ant farm, to keep the 'moth' in.
The atrium and the light are her love. The singer is so in love with her, he doesn't notice he's being cheated and played. She 'loves to watch him fly', meaning she is entertained by how much he loves her.
He thinks she is all his, of course, meaning what he says.
She lets him know she's cheating, but he still loves her.
With the 'powder on the wings' thing, I agree with spoofehness, that is true. I think he is going crazy at that point.
He 'loves her with the way he sings', he tries to get her to fall back into love, but she already has another moth.
