Mark Erickson is Chapin Professor Emeritus from the Geology Department at SLU where he taught Invertebrate Paleontology and Paleoecology for 40 years. His pre-college days were spent learning natural history with an emphasis on the evolutionary design of caterpillar defensive strategies. The sphinx moths have been a focus of that curiosity and this group has remained an avocational interest throughout his career.
