Butterflies.

Okay, it may look as though there are a whole lot of leaves in these trees - but they are all butterflies- millions of them!
Last weekend we went to see a real treasure - the sanctuary of monarch butterflies about 4 hours from mexico city. 150 million butterflies migrate each winter to the same specific place in mexico .. all the way from canada. Butterflies only live 7 months in total, so many of them are born on the 2 month journey between countries.

As we walked through the sanctuary, very quietly, we could hear the faint sound of millions of wings flattering all around us. Magic.
