Stuck in a Chysalis

My caterpillar could be a butterfly by now, but I have no idea since I'm unable to observe him in the greenhouse. He is locked in the science building greenhouse for the weekend. I'm hoping that when I go and check on him tomorrow, that he will be butterfly! I have heard reports from my friends that more of their caterpillars have turned into butterflies on Friday, so maybe that means there is hope for mine.
