Lawrence Reeves, Ph.D., is an entomologist and research assistant scientist at the University of Florida’s Florida Medical Entomology Laboratory. Researchers and mosquito management professionals like Reeves collect samples of mosquitoes across the state to monitor where mosquito species are present and whether new species are entering the state. Here, Reeves uses a large device called an aspirator—”much like a vacuum,” he says—to collect mosquitoes from a wetland habitat. (Photo courtesy of Lawrence Reeves, Ph.D.)
