Diane Frisco, from Dogwood Circle, is raising Monarch Butterflies. She had a question about some of the crystallis turning black. Mary Howe, also from Dogwood Circle, shared a link about the signs and causes of "Black Death". This is a link that should be helpful to all Gardeners: http://www.Insects.About.com. Thanks to Diane and Mary for sharing with us. We are all waiting and watching for the butterflies to return!
