Cover art for Mosquito lyrics by Ingrid Michaelson

I think it is a comparison. She seems to compare a mosquito to a potential lover. "You love like now human could" implies that she has been hurt by love and now feels that a mosquito, a mere insect, is capable of loving better than a human ever could. The second verse then describes her feelings toward said ex lover. She has felt him "poisoning" her. I think that "Wouldn't you love if I fell like Snow White" is her speaking to the ex, saying "wouldn't you love to see me fail?" "How can I truly be angry with you? All you want is to be part of me." I think refers to not only the mosquito but the guy. She is torn, not knowing if she has the right to be angry.
