Black Swallow Tail Butterfly

So as everyone knows Josie really likes butterflies, last year it was all about Monarch butterflies and this year it is all about the Black Swallow Tail butterflies.  Inside Josie's butterfly habitat we had a total of 7 caterpillars and all of them went into cocoons within days of each other.  This was the first one out.  This one is a male you can tell by the colors on the lower part of its wings, it is more yellow than blue.
