Hello! Yesterday I found a praying mantis on my porch, she was in my fern plant. I carefully took her inside, and put her in my enclosure. Right now, she's alone aside for one fly I put in there. The enclosure stands above 4 ft high, 2 ft wide. There is plenty of ventilation, and I added mesh fabric to the top to ensure a safe place for her to molt. I have a hygrometer and thermometer monitoring the enclosure as well. I just want to know, is this even something I should be doing? Should I put her back outside? She doesn't seem to be stressed, but I worry that it's immoral to keep her. Thanks in advance
