Your wings are greener < I like this better now. 
than the faraway willow tree in spring, adorned 
with tails as lissome as a sundown shaft of light, 
only more evasive of a starlit maw. I glow alike < Highlighted part gives me a partial image but does feel abstract. (Forgot to mention last crit.) Not sure what's intended here.
 
and still you came to me. Is it because I have no mouth  < I understand why you changed it to 'came' but I'm a little sad to lose the present tense, where the thoughts of the light are speaking as the creature is nearing.

If I did, I'd only tell you— 
stay on the wall you're settled on. Do not draw too close < Improved. Could possibly be said with fewer words and maybe an image too, and to avoid two "on".
like so many of the grey-winged ones who tap my skin until 
they go up in flares of light and dust. 
 
Get away.

Get away. 
 
You singed your wings 
and morning's here. 

So now I would say keep it present tense for "come to me", because we can probably assume he settled on the wall just after fluttering near. But keep the new ending, I like the change of tense in favor of the time passing until morning. So it's present up to the end. Just my thoughts. 

Another thing I liked is the space you put on the second "Get away" not just to break up the format but made me think about the moth flitting around the light, on this side, that side, this side, alternating around it.
