Please advise a novice on helping an injured butterfly recover?
So, I found a butterfly in the office about 5 hours ago. Initially thought it was dead, it just randomly fell onto my head then the floor. A while later it started flexing it's wings a little so I put a sugarwater-soaked tissue next to it. eventually started moving more and appeared to drink from the tissue. The psychos I work with wanted to throw it out of the window so I brought it home in an improvised cardboard box with some holes in it and more sugarwater tissues, it somehow survived the journey.
Just got it home, it's in a quiet dark place, in the same box with tissues. It can't fly but can move very small distances, and will occationally flex it's wings open. mostly, it stays still with it's wings folded upward. Is there anything I can do to help it, other than leave it alone for a few hours and see if it starts fluttering around so I can release it?
I'm pretty attached to it now, it's name is The Strange Visitor. Any help would be appreciated!
