Thanks, Shortsighted. It was my first time there, so it was sort of like a recon mission. Had to figure out the bus from Kennedy station to the Zoo and then how to get to the park from the Zoo. Simple enough once you know. Over the course of this summer, I've become obsessed with dragonflies. The only other photo I got (aside from the ubiquitous Autumn Meadowhawks) was of a Black-tipped Darner, which had settled on an evergreen shrub near a lake. For butterflies, I saw a mating pair of Pearl Crescents and my first Green Comma, which flew up from the creek bank and settled in a tree in such a way that it was just possible to get a few poor photos. Then it disappeared. The Rouge Valley is also good for turtles--I saw many Midland Painted Turtles, and apparently there are Blandings Turtles there too.
