Haha ! I had a good laugh on this one. It may be even more thoughtful: it could speak about world's injustices, like poor people, stuck in the web of money, power, politics... I don't know if it was your intention but we can see something of it in this Haiku.
I really like this haiku. I think the fact that the moth dies "unnoticed" is the saddest part. You call attention NOT to the death itself, or a painful/gory death, or anything like that, you call attention to the fact that the moth is alone and unseen. I love that - very moving.
