Forensic Entomology: Insects as Silent Witnesses

Natural History Society of Maryland

A career in forensic entomology may not be for the faint of heart, but the study of insects on the postmortem body can yield a wealth of information in criminal cases. Dr. David Rivers, renowned forensic entomologist, will provide an overview of the discipline and then get into ways in which insects have been used in medico-criminal matters, especially homicides, neglect and abuse, and toxicology. David Rivers is Professor of Biology and Director of Forensic Studies at Loyola University Maryland. He received his B.S. in Biology from Ball State University, a Ph.D. in Entomology with a concentration in Insect Physiology from the Ohio State University, and was a NIH post-doctoral fellow in Cellular and Molecular Parasitology at the University of Wisconsin. He is a member of the North American Forensic Entomology Association, Entomological Society of America, and American Academy of Forensic Sciences. He also is co-author of the critically acclaimed textbook The Science of Forensic Entomology and conducts research in several areas involving necrophagous flies and parasitic wasps as they relate to legal investigations. $10 NHSM Members $15 NHSM Non-Members The Natural History Society of Maryland is a volunteer-led non-profit organization, so the fee you pay will go directly to support the programs, the nature collections, and the building that make this kind of nature education possible.

Moss Workshop

If mosses intrigue you when you hike but you wonder exactly what you are seeing, this is your chance to figure it out in a fun environment. On the last Saturday of each month, we'll take a closer look at a moss or two and work together to identify them. We'll introduce you to the vocabulary and work through moss keys together.

Leaders: The sessions will be facilitated by Charlie Davis and Judy Fulton. Charlie is a professional field ecologist who specializes in plants.
