Frequently Asked Questions

Do Butterflies sleep?

  • When butterflies cannot keep their temperatures at activity levels, when it's cloudy, or at night they become quiescent.


  • This quiescence, or resting, is not equivalent to human sleep.


  • Butterflies always have their eyes open, since they do not have eyelids and they probably do not dream.


  • It's probably best just to consider that they become inactive.
