She watched hungry mosquitoes through a plexiglass container as a USDA research scientist talked about pests that love to bug people. Lily and other D.C.-area Girl Scouts visited USDA headquarters to meet women scientists, learn about their work, and discover career possibilities in science, technology, engineering, and math (STEM).
