Mourning Cloak butterfly on our new spruce growth.  This spring has been exceptional for both numbers of species and sheer numbers of butterflies.  On a 15 minute walk in Forestville St. Park this week we saw:    Mourning Cloaks, Monarchs, Commas, Giant Swallowtail, Tiger Swallowtail, Red Admiral, and more-and multiple numbers of each.  Perhaps the mild winter allowed higher survival rates of the overwintering eggs and in somecases overwintering butterflies.
