Did you know - Most butterflies last only two weeks; whereas, the Monarch migrates to Mexico as part of its life cycle. They exclusively host on milkweed and birds will not eat them because of the noxious taste from the milkweed .

The photo on the right is of a Monarch caterpillar on Swamp Milkweed in my backyard. It is one of five different variety milkweed plants that Beth gave me  { These are different from the common milkweed plants that you are all familiar with]

July 2011 -  My daughter Karin was not the only one that noticed that the Swamp Milkweeds were in bloom. She located them on the sandy banks of Kirwan Reservior during a camping trip to West Branch State Park. The park is near Revenna, Ohio.
