Biology professor Steve Murphree led a workshop on Sept. 15 at the Owl’s Hill Nature Sanctuary. The workshop was titled The World of Invertebrates: Pollinators, Predators, Pests and Parasitoids and had 25 adult student participants. The students learned about the characteristics and life cycles of insects, how to identify insects using keys, had an overview of other arthropods (spiders, isopods, mites, etc.), discovered methods of collecting and observing insects and other arthropods and learned about the ecological roles of arthropods. The workshop was part of the 2012-13 Tennessee Naturalist program at Owl’s Hill Nature Sanctuary. This is the third year Murphree has been an instructor in this program.
