A Line Of Busy Ants

What I saw from my window. Week 11: Dorsimbra

         A line of ants, industriously stretched
         along my sill, dashes of black business.
         A scout was sent, the whole colony fetched,
         to tramp unquestioning to food’s address.

         Endless wave, in steadfast wriggly line -
         a grain borne away in stoic triumph;
         and yet behind, pour more brethren in search of that
         sticky bounty of careless coffee mug on sill.

         Probing fingers gently lift up spoon.
         Suddenly, scattering swirling ant flight -
         abandonment of aim, affirms defeat.
         Today they’re gone, future - who knows or cares?
