The period of that a chrysalis takes to make the transformation was reputed to be about 2 weeks, and that proved to be the magic number. Over the last several days, the chrysalis started getting darker, as the dark winged and dark bodied butterfly inside took it's final shape.
This time we missed the change. I was in the shower when Georgia came up and reported that the butterfly had emerged (TMI?).
Ladies and Gentlepersons, the butterfly:
You can see the classic red and black bulls eye mark at the back of the rear wing, and the complete row of orange spots, with the doubled up spot that clearly distinguish this from the similar Spicebush Swallowtail.
It chose a rather difficult day to emerge. It's struggling to get over 60 F today, considered a minimum temperature for most butterflies to fly, in the wake of a cold front that passed through yesterday. Hopefully, by the time it's wings have fully dried and hardened, it will be warm enough to fly off.
