Can potato beetles be pets

Potato beetles probably can not eat lettuce. Potato beetles evolved in the Rocky Mountains of North America. They could only live on a plant similar to a potato. When farmers began growing potatoes, they moved to potato plants. They were able to live on their original hosts as well as potato plants. In fact, potato plants provided a better place for them. So, the fact that they were unable to spread until they could move to potato plants makes it seem like it will be difficult to find somewhere else they can grow.
