Ladybugs Have a Killer Secret

Discover the killer instincts of ladybugs with our Insectarium host and American Museum of Natural History Curator, Jessica Ware. She visits Dr. Sara Hermann's lab at Penn State University, where researchers are studying predator-prey relationships, like that of ladybugs and aphids. In addition to chowing down on plant pests, ladybugs hold potential to help sustainably protect food crops via the chemical cocktails they naturally produce—kind of like a "perfume of fear."
