<human>:  I have a question about raising butterflies. Why do I have to keep the butterfly in a dark box?
<bot>: Butterflies are nocturnal, so they need to be kept in a dark box to avoid being eaten by predators. They also need to be kept in a warm, humid environment, so they can regulate their body temperature.
