A wrong-sized poem

Elephantine insect larva are a frightful sight
Because they counter physics in a way that isn’t right.
Perhaps you’ve never contemplated scale’s inner laws,
Yet deep inside you understand that small things have no claws.
You know that tiny things can flutter, larger ones can flap,
But giant ones will plummet or have wings so large they’d snap.
I doubt that you were taught all this, but deep inside you know
It takes a redesign of form to safely vastly grow.
