Edith and her husband Stephen have been butterfly farming for over 18 years. Their farm, co-owned with their daughter Charlotte, raises 30 species per year. In addition to raising butterflies, Edith searches the fields and woods for anything she hasn’t raised and in the process, has learned a good deal about diseases and parasitoids.
Edith has been teaching this course every year since 2007. Each year it is updated with new photographs added to illustrate diseases and everything that pertains to disease in butterflies and raising butterflies.
Edith worked with Dr. Leellen Solter and Amanda Lawrence as they edited the material before it was offered as a course. The OE material was edited by Dr. Sonia Altizer and Dr. Karen Oberhauser first as a presentation (presented by Edith) at an AFB Symposium.
