Monarchs on the move

There have been a lot of monarch butterflies around town this week, enjoying the perfect fall weather.  According to Wikipedia, the one pictured here is a female (darker veins) and she deposits her eggs as she migrates south.  I also learned that the name came from Samuel H. Scudderin 1874 because "it is one of the largest of our butterflies, and rules a vast domain." Although it might also be named in honour of King William, Prince of Orange.  Either way, it's a favorite sign of the season.
