This whole poem is about being perceived as a girl, and a pretty girl at that, by certain people. the references to "rhopalocera" aka a butterfly just represent how when your feel seen you feel like you need to flee. Lines 11-14 reference how being a girl can feel like you are inside of a shadowbox and it's not pleasant to me picked apart. Whenever you are seen as close to perfect people like to tear that down and find all the unpleasant things about you. Snow globes, fishtanks, and shadowboxes all share a few things; Your supposed to look at these things and it's supposed to be beautiful and see-through. Unlike ordinary things, these things usually imply depth, so you observe for deeper things. Perfection is not a real thing, and to add, the outlook of it is overrated. Nothing can be the only everything to someone. Putting yourself in the hierarchy is just tearing you apart further. The golden standard should not be measurable, especially since it changes so often. A dragonfly surpasses a butterflies beauty in it's own way, but the two should not be compared in the first place. With the line "What do you think?" it wraps everything up in a nice bow and sort of explaining how after saying all this, I still care what everyone thinks. I still wound up in this vanity crypt because I care so genuinely about what the world, and the people I hold closest, think.
