Describe symbolism in Bluish by Virginia Hamilton

The Blue Morpho is a symbol for Bluish's struggle, and perhaps for Bluish herself. Like the butterfly, Bluish is filled with a poison, of a sort, that makes others fearful of her. But also like the butterfly, Bluish is beautiful and special, no matter the toxicity lurking underneath. As with Max's explanation that the exotic coloring of the Blue Morpho indicates toxicity, the author may imply that it is the very fact of Bluish's toxicity that has made her special, and that Bluish's mighty struggle has resulted in a strong, kind, wise person.
