Thank you
@DeborahJane. When the butterflies first exit the chrysalis, the thorax (abdomen) is enormous and the wings are small, all crumpled up, and limp. The reason the thorax is so huge is that it is full of fluid part meconium from their stay in the chrysalis which they pee out (in a magnificent arch for these butterflies because of their size). The first time i saw that, i said "well hello"
. The remaining fluid is flowing into veins in the wings (hence the "hanging"), expanding the wings and making them flight ready. The time this takes depends on the air temperature and the size of the butterfly. It could be an hour before they are ready to fly. The butterflies are so vulnerable during this time. If they should loose their grasp and fall down while the wings are still limp, they will die unless they have a friend passing by to offer them a finger to grasp or unless there is something to climb on that they can drag themselves to. The larger bflies like this one rarely fall but sometimes the smaller to mid sized ones do. Gosh i hope this is coherent. I am so stunned by what has just happened in the country of my birth that i am both sick to my stomach and light headed, and in a state of disbelief. The person who will not be the president received the majority of the popular vote, but the candidate who becomes president is the one who receives the most electoral votes.
