i love this
suicide season ? brilliant. ive never heard that before . i really like how it was used in the poem.
excellent job

I like this :). All the metaphors are good and it keeps a nice kind of flow. The kind of flow that is essential to all none rhyming poems. Now, to the other stuff. The only thing that really stuck out to me was the last verse:

"I will not speak for my darling dead moths
they will gather in my throat and eat my voice
only the whisper of their haunted wings will remain "

I think it just needs to be phrased a little differently. The rest of the poem is soo..I can't really explain it but its that flow again I guess, it just has a lot of elegance. This last verse looses that flow a little bit when it switches to your point of view so I think it needs some dressing up, something like:

"I’ll speak not for my darling dead moths
they will gather in my throat and eat my voice
only the whisper of their haunted wings will remain
marking all their little graves"

That’s just a suggestion though so you don't have to take it too seriously(its my sad effort at constructive criticism). Still I really like this poem and you get extra points for using moths, I love moths.
