Death+comes+in+a+day+or+two.

This line, as the one before, again creates a tone that seems ominous. Death is coming, and fast. But is it the death of a person that will arrive in the alotted two days time, or something else? Millay speaks of the blue and white butterflies in the first line of the poem and characteristically the small blue butterfly, known as the copper butterfly, is known to have the shortest lifespan of the species; a couple days. It seems then that Millay might be referring to the insect that death comes for.
