I must disagree. It was proved many times, ants in captivity lived as normal in day light. Their instinct is quite flexible, and the ants which aren't used to darkness don't associate light with danger. If you put ants into nest in which they can dig, they often dig also near the glass, and new corridors which THEY make are open to light. This means they don't necessary choose darkness even if they have choice. There is only problem with agressive ants wich particulary good sight, like Formica or Myrmecia, which sometimes react to human motion. That's why sometimes is better to keep them covered, but the light itself doesn't harm them in any way. Most ants use their eyes mostly for navigation outside nest and don't react to motion. It is easy to recognize if ants feel safe - if they are calm, they feed larvae and clean them, and the queens lay eggs it means they feel comofortable and aren't afraid of anything.
