These butterflies and their offspring can still remember a mass they’ve never seen, sound waves breaking just so, and fly out of the way. How did they pass on this knowledge of the invisible? Does this message transmit through the song they sing to themselves on their first wild nights, spinning inside a chrysalis? Or in the music kissed down their backs as they crack themselves open to the morning sun? Does milkweed whisper instructions to them as it scatters in the meadow?
