Not a good year for Monarchs

We had 16 eggs laid on the milkweed and only one successful caterpillar to butterfly.  I read a news story that there were forest fires in Mexico that reduced the Monarch population, (http://news.bbc.co.uk/2/hi/americas/754853.stm), and that is why there weren't as many butterflies this season.  So sad.  Here's hoping for next year!
