This is the "Monarch Butterfly".  We are honored to have them stop in our flower garden every Spring.  If you don't know the incredible story of the Monarch Butterfly you should look them up on the internet.  This butterfly has flown over a thousand miles from Canada to get to Texas and it still has nine hundred more miles to fly to get to one placed in Mexico.  They stay in Mexico for five months then return to Texas to mate and die, there offspring continue the journey on to Canada to start the cycle all over again.  No one knows how they navigate that very long distance.  It is quite an incredible story.
