Monarchs are beautiful butterflies.
There's evidence in this photograph about the gender of the butterfly, and about the weather that day. What do you think?
If you are interested in the long migrations made by monarch butterflies, take a look at the NOVA TV program The Incredible Journey of the Butterflies. When I first went to this link there was only a preview, but today you can watch what looks like the entire the show. I hope to finish it soon.
After the show, you might want to pick up one of these. There are a lot of great children's books about monarch butterflies.
