First sighting of question mark butterfly in 2013!!!

This is one of two butterflies that I have still been waiting to see all summer! I am thrilled to have spotted her today on the side of my neighbor's house. The tiger swallowtail is the other species that I normally see in my backyard all summer but one I haven't eyed yet. In past years we have raised both question marks and a tiger swallowtail. I have left an elm sapling beside my gate in case the question mark needed it as a host plant. Maybe there is still hope this summer for more question marks and some tigers!
