Butterflies don't recognize their owners. Butterflies have a very small brain capacity and cannot recognize people. They will not recognize their owners no matter how long they are kept. Moreover, the life span of butterflies is not very long, the longest is only about half a year. If they are not raised well, they will die in two or three days, so they must be raised carefully and scientifically.
Notes on raising butterflies:
1. Ventilation
To raise butterflies, choose a place with good ventilation, sufficient light, and a certain humidity. Environment, and protective measures must be taken to prevent butterflies from flying away.
2. Food
Domestic butterflies can be fed nectar, honey water, syrup, milk, and fruits. You can apply honey water or syrup water on leaves or flowers. Butterflies feed themselves.
3. Taboos

Be careful when raising butterflies. Do not light mosquito coils or use any insecticide products indoors, otherwise the butterflies will die.
