Hello, my sphodromantis lineola has recently gotten very "flighty". He/she moves very fast and freaks out some times(just goes super fast). This happened right after I finished feeding, I actually lost a mantis for the first time, don't worry I found him after much stress, he was right were I lost him ironically. And recently I put him in a vivarium that I set up for my ghosts coming in(it is way to big for him), and just recently when I went to check on him he freaked out when he saw me and started sprinting around(second time this happened). So my question is, is this just a behavioral thing for the speices or is he stressed with such a big enclosure? Or maybe something else?
