Revis Ridge Field Trip

Saturday, April 27th, 2013

On Saturday, April 27, 2013, we visited the Revis Ridge Nature Preserve (near Springfield, Illinois). Here are some of the photos Mark DuBois took during the excursion. To view more, click on any photo. You will be taken to Mark’s Flickr site where you can view the entire set as a slide show (or as a series of larger images). We were seeking zebra swallowtail butterflies to photograph, but did not encounter any. It was rather overcast and threatening rain most of the time we were there. We hope you enjoy these photos. Consider joining our group on our next excursion.
