Lady bugs

so, I have this family of ladybugs living in my bathroom. There's probably ten or more in total, different sizes too. There are also a few aphids/fruit flies in this same corner which I think the ladybugs are feeding on. It's like there is a mini-food chain thing going on. It's nice and warm and humid, not a bad place to live.
What I find interesting is if they were ants or mice or some other bug I might try to rid myself of them thinking they're pests, but because they're these pretty little bugs I like them and so they stay there, is it their beauty that I admire. Do you have any bugs that you live with or tolerate? If I look at my yard there are all these groupings of animals and bugs and birds, we all seem to get along, even the wasps and the bees have a place. Ecosystems
