Thinking about the possibility of applying to get my indoor garden certified as wildlife habitat, I realized for it to be true I'd need to be doing more than simply providing habitat for my frog food and microbes in my potted plants. I need to be providing shelter to wildlife. So, I can do local millipedes, pillbugs, and Cecropia moths, and release them when the habitat gets crowded. This would mean I would have cocoons to flatten into hankies, if I can get native cherry to grow indoors.
