I debated whether to intervene or not, regarding the Monarch Butterfly chrysalis. The weather here in Houston was very cold this past week, so I decided to bring this monarch inside about a week ago. I tied some thread to the chrysalis and placed it inside a small 15x15x15 cube photo box I had. I am not sure if it will survive, but it does appear to be darkening slowly which would be a sign that it was getting ready to emerge. I noticed more detail today of its wings. Granted it has been over a month now since it began the pupa stage but January was cold and perhaps it slowed down its transformation. I do hope this little one makes it. I have a larger photo cube 30x30x30 where I plan to keep it until the weather warms a bit. A few blooming plants from the nursery should provide enough nectar, but if not, I have found some websites detailing how to feed them if necessary.
