Butterflies are no strangers to Milwaukee. You can find them everywhere, from backyards to the great butterfly room at the Milwaukee Public Museum. But right now, the Milwaukee County Zoo is hosting more than 500 butterflies from across North America and the Caribbean in its new exhibition, "Butterflies! In Living Color," which runs through Sept. 25 in the Otto Borchert Family Special Exhibition Building (next to monkey island and the sea lion show).
