The earlier pictures I took of swallow tail butterfly eggs proved not to get to far. The birds usually pick them off in the earlier part of the season. I have been watching closely and the last set of eggs has made it to the next stage. Picture on the left is from June 9 and the picture on the right is from today. The difference is the color and the pronounced white stripe. In a few days we should see the orange dots that run down it's back. And yes, these are the same three fellows.
