I know I had some good reason for leaving the top off the butterfly rearing tank ajar.
But, at the moment, when I have a transforming caterpillar tethered to my wall, I can't remember what I was thinking.
I figure I'll let the caterpillar shed its skin and then I'll carefully cut it off the the wall. I'm too worried about damaging the animal, while it is re-assembling its insides, to take any action right now.
This is normal, right? You all have caterpillars stuck to the walls of your house, don't you?
