Nector and pollen. Let the butterfly out or you will kill it.

Depending on the species of butterfly it is. I would actually let the butterfly go because then it wont starve to death or anything else in this temp habitat that might harm it. Butterflies tend to eat flower nectar, and because it uses a proboscis like a fly does, there is no way it can eat a stick. Special butterfly food are mixed with water and are put on a plate where they can eat it. Other butterflies may eat some sort of mashed up leaves but keep this in mind: ONE TYPE OF BUTTERFLY WILL ONLY EAT CERTAIN FOODS. So identify your butterfly, dosome research and then feed it. But also, food is not enough. Air and the freedom to move around is other elements for keeping butterflies.
