It is effectively the name of a group of butterflies (hipsypile) and that of a Greek princess (Hipsípila) but there is no known mythological relationship between them, and apparently their only link is the name assigned by the entomologist to these insects. The reason Darius amalgamates them in his poem is metaphorical: he equates the filial and maternal suffering of the princess with that of the dissatisfied in Love by making unfortunate events become a kind of transformative chrysalis from which a new person emerges, more strengthened perhaps. Rubén Darío belonged to the Modernist literary movement, where references to Oriental and Greek themes were frequent.
